Mattis was nominated as secretary of defense by president-electDonald Trump, and confirmed by the Senate on January 20, 2017. As secretary of defense, Mattis affirmed the United States' commitment to defending longtime allySouth Korea in the wake of the2017 North Korea crisis.[7][8] An opponent of proposed collaboration withChina andRussia,[9] Mattis stressed what he saw as their "threat to the American-led world order".[10] Mattis occasionally voiced his disagreement with certain Trump administration policies such as the withdrawal from theIran nuclear deal,[11] withdrawals of troops from Syria and Afghanistan,[12] and budget cuts hampering the ability tomonitor the impacts of climate change.[13][14] According toThe Hill, Mattis also reportedly dissuaded Trump from attempting to assassinateBashar al-Assad, thepresident of Syria.[15]
On December 20, 2018, after failing to convince Trump to reconsider his decision to withdraw all American troops from Syria, Mattis announced his resignation effective the end of February 2019; after Mattis's resignation generated significant media coverage, Trump abruptly accelerated Mattis's departure date to January 1, 2019, stating that he had essentially fired Mattis.[16]
Mattis is a graduate of the US Marine Corps Amphibious Warfare School,US Marine Corps Command and Staff College, and theNational War College. He is noted for his interest in the study ofmilitary history andworld history,[37][38] with a personal library that once included over 7,000 volumes,[2] and a penchant for publishing required reading lists for Marines under his command.[39][40] He required his Marines to be well-read in the culture and history of regions where they were deployed, and had his Marines deploying to Iraq undergo "cultural sensitivity training".[38] According to an article published in 2004 by theLos Angeles Times it was his concern for the enlisted ranks along with his energy and enthusiasm that garnered him the nickname "Mad Dog".[4][5] But in 2016, when President-elect Trump asked Mattis if his nickname was indeed "Mad Dog", Mattis replied, "No, sir," saying that his actual nickname was "Chaos".[41]
Mattis led the1st Marine Expeditionary Brigade as its commanding officer upon promotion to brigadier general.[42] It was as a regimental commander that he earned his nickname and call sign, "CHAOS", an acronym for "Colonel Has Another Outstanding Solution", which was initially somewhat tongue in cheek.[43]
During the initial planning for the War in Afghanistan, Mattis led Task Force 58 in operations in the southern part of the country beginning in November 2001.[44] This led to him becoming the first Marine Corps officer to command a Naval Task Force in combat.[31] According to Mattis, his objective upon arriving in Afghanistan was to "make sure that the enemy didn't feel like they had any safe haven, to destroy their sense of security in southern Afghanistan, to isolateKandahar from its lines of communication, and to move against Kandahar".[45] In December 2001, an airstrike carried out by aB-52 bomber inadvertently targeted a position held by USspecial operations troops and Afghan militiamen inUruzgan Province. Numerous men were wounded in the incident, but Mattis repeatedly refused to dispatch helicopters from the nearbyCamp Rhino to recover them, citing operational safety concerns. Instead, an Air Force helicopter flew fromUzbekistan to ferry the men to theMarine Corps base where helicopters sat readily available but unauthorized to fly. CaptainJason Amerine blamed the delay caused by Mattis's refusal to order a rescue operation for the deaths of several men. Amerine wrote, "Every element in Afghanistan tried to help us except the closest friendly unit, commanded by Mattis," though he also wrote that "none of that was assessed properly because the [5th Special Forces Group] chose not to call for a formal investigation".[46][47] This episode was used against Mattis when he was nominated for defense secretary in 2016.[48]
While serving in Afghanistan as abrigadier general, Mattis was known as an officer who engaged his men with "real leadership".[49] A young Marine officer,Nathaniel Fick, said he witnessed Mattis in afighting hole talking with a sergeant and lance corporal: "No one would have questioned Mattis if he'd slept eight hours each night in a private room, to be woken each morning by an aide who ironed his uniforms and heated hisMREs. But there he was, in the middle of a freezing night, out on the lines with his Marines."[50]
In May 2004, Mattis ordered the 3 a.m. bombing of what his intelligence section had reported was a suspected enemysafe house near the Syrian border, but was later reported to bea wedding party and allegedly resulted in the deaths of 42 civilians, including 11 women and 14 children. Mattis said it had taken him 30 seconds to decide whether to bomb the location. Describing the wedding as implausible, he said, "How many people go to the middle of the desert to hold a wedding 80 miles (130 km) from the nearest civilization? These were more than two dozen military-age males. Let's not be naive."[52] The occurrence of a wedding was disputed by military officials, but theAssociated Press obtained video footage showing a wedding party and a video the next day showed musical instruments and party decoration among the remains.[53] When asked by the press about footage on Arabic television of a child's body being lowered into a grave, he replied: "I have not seen the pictures but bad things happen in wars. I don't have to apologize for the conduct of my men."[54]
Following a Department of Defense survey that showed only 55% of US soldiers and 40% of Marines would report a colleague for abusing civilians, Mattis told Marines in May 2007 that "whenever you show anger or disgust toward civilians, it's a victory foral-Qaeda and other insurgents." Believing that a need for restraint in war as key to defeating an insurgency, he added: "every time you wave at an Iraqi civilian,al-Qaeda rolls over in its grave."[55]
1st Marine Division's motto "no better friend, no worse enemy"
Mattis popularized the1st Marine Division's motto "no better friend, no worse enemy", a paraphrase of the epitaph theRoman dictatorLucius Cornelius Sulla wrote for himself,[56] in his open letter to all men within the division for their return to Iraq. This phrase later became widely publicized during the investigation into the conduct of LieutenantIlario Pantano, a platoon commander serving under Mattis.[57][58][59][60][61]
As his division prepared to ship out, Mattis called in "experts on the Middle East" for "cultural sensitivity training". He constantly toured the battlefield to tell stories of Marines who were able to show "discretion in moments of high pressure". As an apparent example, he encouraged his Marines to grow moustaches to look more like the people they were working with.[38]
He was also noted for a willingness to remove senior leaders under his command when the US military seemed unable or unwilling to relieve underperforming or incompetent officers. During the division's push to Baghdad, Mattis relieved Colonel Joe D. Dowdy, commander ofRegimental Combat Team-1. It was such a rare occurrence in the modern military that it made the front page of newspapers. Despite this, Mattis declined to comment on the matter publicly other than to say that the practice of officer relief remains alive, or at least "we are doing it in the Marines."[50] Later interviews of Dowdy's officers and men revealed that "the colonel was doomed partly by an age-old wartime tension: Men versus mission—in which he favored his men," while Mattis insisted on execution of the mission to seize Baghdad swiftly.[62]
After being promoted tolieutenant general, Mattis took command ofMarine Corps Combat Development Command. In February 2005, speaking at a forum inSan Diego, he said, "Actually it's quite fun to fight them, you know. It's a hell of a hoot. It's fun to shoot some people. I'll be right up there with you. I like brawling. You go into Afghanistan, you got guys who slap women around for five years because they didn't wear a veil. You know, guys like that ain't got no manhood left anyway. So it's a hell of a lot of fun to shoot them."[63] Mattis's remarks sparked controversy; GeneralMichael Hagee,commandant of the Marine Corps, issued a statement suggesting Mattis should have chosen his words more carefully, but he would not be disciplined.[64]
Mattis was promoted to four-star general and took control ofUSJFCOM/SACT on November 9, 2007. On September 9, 2009, French Air Force GeneralStéphane Abrial assumed the position of SACT. Mattis remained commander of JFCOM from November 2007 until September 2010.[66]
Mattis took command at a ceremony atMacDill Air Force Base on August 11.[70][71][72] As head of Central Command, Mattis oversaw the wars in Iraq and Afghanistan and was responsible for a region that includesSyria, Iran, and Yemen.[73] He lobbied the Obama administration for a more aggressive response to Iran, including more covert operations and disruption of Iranian arms shipments to Syria andYemen.[74] After an incident in 2011 where an Iranian jet had attacked a U.S. drone flying over thePersian Gulf in international airspace, Mattis wanted permission to shoot down any Iranian aircraft that was attacking American drones, but theObama administration denied this request.[75] According toLeon Panetta, the Obama administration did not place much trust in Mattis because he was perceived as too eager for a military confrontation withIran.[76] Panetta later said, though, that some of the mistrust was unjustified, arising from the inexperience of some White House staff not understanding the need "to look at all of the options that a president should look at in order to make the right decisions." Nevertheless, Mattis's hawkishness was out of step with the White House's perspective, and "ultimately, Mattis's advocacy and aggressive style alienated the White House and the president he was serving."[77]
Mattis retired in March 2013, and the Defense Department nominated GeneralLloyd Austin to succeed him.[78] Sheikh Моhamed bin Zayed al-Nahyan asked Mattis to serve as a military advisor in the Yemen war conflict. During Mattis's tenure as the Secretary of Defense underPresident Trump, his consultation with the UАЕ was omitted from public record and financial disclosure. Mattis's relationship with the UАЕ was strong, featuring a speech in Аbu Dhаbi initially set to be compensated at $100,000 but later clarified as unpaid.[79]
After retiring from the military, Mattis worked for FWA Consultants and served as a member of theGeneral Dynamics Board of Directors.[80] Between 2013 and 2017, while on the board ofGeneral Dynamics, Mattis made more than $900,000 in compensation, including company stock.[81] In August 2013, he was appointed an Annenberg Distinguished Visiting Fellow at theHoover Institution[82] and in 2016 he was named the Davies Family Distinguished Visiting Fellow.[83]
He is co-editor of the bookWarriors & Citizens: American Views of Our Military, published in August 2016.[85]
From 2013 to January 2017, Mattis was a board member ofTheranos, ahealth technology company that claimed to have devised revolutionaryblood tests using very small amounts of blood, which was later determined to be a fraudulent claim by theUS Securities and Exchange Commission.[86][87][88][89][90] Previously, in mid-2012, a Department of Defense official evaluating Theranos's blood-testing technology for the military initiated a formal inquiry with theFood and Drug Administration about the company's intent to distribute its tests withoutFDA clearance. In August 2012, Theranos CEOElizabeth Holmes asked Mattis, who had expressed interest in testing Theranos's technology in combat areas, to help. Within hours, Mattis forwarded his email exchange with Holmes to military officials, asking "how do we overcome this new obstacle". In July 2013, the Department of Defense gave Mattis permission to join Theranos's board provided he did not represent Theranos with regard to the blood-testing device and its potential acquisition by the Departments of the Navy or Defense.[91]
In 2019, Mattis's bookCall Sign Chaos: Learning to Lead was published.[92] It is an autobiography as well as an argument in favor of aninternationalist foreign policy.[93] On August 7, 2019, Mattis was re-elected to the board ofGeneral Dynamics.[94]
Mattis with PresidentTrump and Vice PresidentPence
President-electDonald Trump met with Mattis for a little over one hour inBedminster, New Jersey, on November 20, 2016.[95] He later wrote onTwitter, "General James 'Mad Dog' Mattis, who is being considered for secretary of defense, was very impressive yesterday. A true General's General!"[96] On December 1, 2016, Trump announced at a rally in Cincinnati that he would nominate Mattis for secretary of defense.[97]
TheNational Security Act of 1947 requires a seven-year waiting period before retired military personnel can assume the role of secretary of defense; Mattis's nomination meant that it was the first time since 1950 (in that instance forGeorge Marshall) that a waiver of the law was needed.[97][98] The waiver for Mattis passed 81–17 in the Senate and 268–151 in the House. Mattis was subsequently confirmed as secretary of defense by a vote of 98–1 in the United States Senate on January 20, 2017.[99] SenatorKirsten Gillibrand was the sole "no" vote,[100] stating that she was opposed to the waiver on principle,[101] though she would vote to confirmLloyd Austin for the same position in 2021, having only been out of the Army since 2016.[102]
For his first official trip abroad, Mattis began a two-day visit with longtime US allySouth Korea on February 2, 2017.[7] He warnedNorth Korea that "any attack on the United States, or our allies, will be defeated", and any use of nuclear weapons would be met with an "effective and overwhelming" response from the United States.[8] During a press conference inLondon on March 31, 2017, with the Britishsecretary of state for defence,Michael Fallon, Mattis said North Korea was behaving "in a very reckless manner" and must be stopped.[104] During a Pentagon news conference on May 26, Mattis reported the US was working with the UN, China, Japan, and South Korea to avoid "a military solution" with North Korea.[105] On June 3, Mattis said the United States regarded North Korea as "clear and present danger" during a speech at the international security conference inSingapore.[106] In a June 12 written statement to theHouse Armed Services Committee Mattis said North Korea was the "most urgent and dangerous threat to peace and security".[107] On June 15, Mattis said the US would win a war against North Korea, but "at great cost".[108]
On March 22, 2017, during questioning from the US Senate, Mattis affirmed his support for US troops remaining in Iraq after theBattle of Mosul was concluded.[109] Mattis responded to critics who suggested the Trump administration had loosened therules of engagement for theUS military in Iraq after US-led coalitionairstrikes in Mosul killed civilians,[110] saying, "We go out of our way to always do everything humanly possible to reduce the loss of life or injury among innocent people."[111] According toAirwars, the US-led coalition killed as many as 6,000 civilians in Iraq and Syria in 2017.[112]

On April 5, 2017, Mattis called theKhan Shaykhun chemical attack "a heinous act", and said it would be treated accordingly.[113] On April 10, Mattis warned the Syrian government against usingchemical weapons again.[114] The following day, Mattis gave his first Pentagon news conference since becoming secretary of defense, sayingISIL's defeat remained "our priority", and the Syrian government would pay a "very, very stiff price" for further usage of chemical weapons.[115] On April 21 Mattis said Syria still had chemical weapons and was in violation of United Nations Security Council resolutions.[116] According to investigative journalistBob Woodward, Trump ordered Mattis to assassinate Assad, but Mattis refused.[117] On May 8 Mattis told reporters details of the proposed Syrian safe zones were "all in process right now" and the United States was involved with configuring them.[118]
On April 20, 2017, one week after theNangarhar airstrike, Mattis told reporters that the US would not conduct a damage assessment "in terms of the number of people killed" in Afghanistan.[121] Mattis traveled to Afghanistan days later and met with government officials, explaining that the purpose of the trip was to allow him to state his recommendations for US strategy in the country.[122] On June 13, Mattis said US forces were "not winning" in Afghanistan and the administration would develop a new strategy by "mid-July" while speaking to theUnited States Senate Committee on Armed Services.[123] On June 29, Mattis said the Obama administration "may have pulled our troops out too rapidly" and that he intended to submit a new Afghanistan strategy to Trump upon his return to Washington, D.C.[124]
The United States has been openly arming theSyrian Kurdish fighters in the war againstISIL since May 2017.[125] Following the start of theTurkish invasion of northern Syria aimed at ousting US-backed Syrian Kurds from the enclave ofAfrin, Mattis said in January 2018: "Turkey is a NATO ally. It's the only NATO country with an active insurgency inside its borders. And Turkey has legitimate security concerns."[126] Turkish Deputy Prime MinisterBekir Bozdağ urged the United States to halt its support for KurdishYPG fighters, saying: "Those who support the terrorist organization will become a target in this battle."[127]
On April 13, 2018, Mattis briefed reporters in a press conference at the Pentagon on the2018 missile strikes against Syria being carried out against the Assad regime's chemical weapon compounds, saying, "Tonight, France, the United Kingdom and the United States took decisive action to strike the Syrian chemical weapons infrastructure. Clearly the Assad regime did not get the message last year. This time our allies and we have struck harder. Together we have sent a clear message to Assad and his murderous lieutenants that they should not perpetrate another chemical weapons attack for which they will be held accountable".[128]
In November 2018, theCIA assessed with "high confidence" thatSaudi Arabia's Crown PrinceMohammad bin Salman ordered the assassination ofWashington Post columnistJamal Khashoggi.[129] Under mounting pressure from lawmakers who wanted action against Saudi Arabia, Mattis and Secretary of StateMike Pompeo, in a rare closed briefing of the Senate, disputed the CIA's conclusion and declared there was no direct evidence linking the crown prince to Khashoggi's assassination.[130]
Wherever Mattis traveled overseas, he brought theDefense Security Cooperation Agency director (the official in charge of weapon sales to foreign governments), according to Lt. Gen. Charles Hooper, speaking at the Brookings Institution in June 2019.[131]
On December 19, 2018, Trump announced immediateUS withdrawal from Syria, over his national security advisers' objections.[134] Mattis had recently said that the US would remain in Syria after ISIL's defeat to ensure it did not regroup. The next day, he submitted his resignation after failing to persuade Trump to reconsider.[135][136] His resignation letter contained language that appeared to criticize Trump's worldview—praising NATO, which Trump has often derided, and the 79-nation anti-ISIS coalition that Trump had decided to leave. Mattis also affirmed the need for "treating allies with respect and also being clear-eyed about both malign actors and strategic competitors" and remaining "resolute and unambiguous" against authoritarian states such as China and Russia. He wrote that Trump has "the right to have a Secretary of Defense whose views are better aligned with [his] on these and other subjects."[137][138] His resignation triggered alarm among historical allies.[139] In his 2018 resignation letter, Mattis called both Russia and China "authoritarian models" rivaling US interests.[140] Mattis's letter said his resignation would be effective February 28, 2019.[141] Three days later Trump moved Mattis's departure date up to January 1, after becoming angered by the implicit criticism of Trump's worldview in Mattis's letter.[142] On January 2, 2019, Trump criticized Mattis's performance as secretary of defense and said he had "essentially fired him".[143]
John F. Kelly, Trump's chief of staff when Mattis left his position, denied that Trump fired Mattis or asked for his resignation. He said Trump must be confused or mistaken, and that "Jim Mattis is an honorable man".[144] Mattis returned to his post as Davies Family Distinguished Fellow at theHoover Institution.[145]
After leaving the White House, Mattis initially declined to offer his opinion of the Trump administration, saying, "If you leave an administration, you owe some silence,"[146] and was guarded when asked to reflect on Trump or military matters, saying he didn't want to detract from the troops.[147] He changed his position after becoming "angry and appalled" about the events leading up to the violent treatment of noncombative protesters near the White House on June 1, 2020, for the purpose of a photo op for Trump at the church across Lafayette Square.[148] Trump responded by Twitter that evening that he "felt great" he had previously asked Mattis to resign, and he didn't like much about Mattis or his "leadership style" and was "Glad he is gone!"[147]
In 2019, Mattis joined The Cohen Group as senior counsel.[149][150][151]
Mattis, along with all other living former secretaries of defense, ten in total, published aWashington Post op-ed piece in January 2021 telling President Trump not to involve the military in determining the outcome of the 2020 elections.[152]
I'm not just an overrated general, I am the greatest, the world's most overrated... I'm honored to be considered that by Donald Trump, because he also calledMeryl Streep an overrated actress. So I guess I'm the Meryl Streep of generals, and frankly, that sounds pretty good to me. And you do have to admit that between me and Meryl, at least we've had some victories.[153]
He continued, "I've earned my spurs on the battlefield... Donald Trump earned his spurs in a letter from a doctor."[154]
Mattis claimed he has "never registered for any political party". He also claimed that as a member of the U.S. military, he was "proudly apolitical".[155]
Mattis said in 2020 that Donald Trump is "the first president in my lifetime who does not try to unite the American people — does not even pretend to try. Instead he tries to divide us." After theJanuary 6 attack, Mattis said Trump used the presidency to "destroy trust in our election and to poison our respect for fellow citizens." In 2024, after former chairman of theJoint Chiefs of StaffMark Milley called Trump "fascist to the core" and "the most dangerous person ever", authorBob Woodward said Mattis had emailed him to second Milley's assessment.[156]
Mattis supports atwo-state solution model forIsraeli–Palestinian peace. He has said the situation in Israel is "unsustainable" and thatIsraeli settlements harm prospects for peace and could lead to an apartheid-like situation in theWest Bank.[157] In particular, he has said that the perception of biased American support for Israel has made it difficult for moderate Arabs to show support for the United States. Mattis strongly supported Secretary of StateJohn Kerry on the Middle East peace process, praising Kerry for being "wisely focused like a laser beam" on a two-state solution.[158]
Mattis believesIran is the principal threat to the stability of the Middle East, ahead ofAl-Qaeda andISIL. Mattis says: "I consider ISIS nothing more than an excuse for Iran to continue its mischief. Iran is not an enemy of ISIS. They have a lot to gain from the turmoil in the region that ISIS creates." Mattis sees theIran nuclear deal as a poor agreement, but believes there is now no way to tear it up, saying: "We are just going to have to recognize that we have an imperfect arms control agreement. Second, that what we achieved is a nuclear pause, not a nuclear halt". Mattis argues that inspections may fail to prevent Iran from seeking to develop nuclear weapons, but that "[i]f nothing else at least we will have better-targeting data if it comes to a fight in the future."[11] Additionally, he criticized Obama for being "naive" about Iranian intentions and Congress for being "pretty much absent" on the nuclear deal.[159]
Mattis praises the friendship of regional US allies such asJordan,Israel, and theUnited Arab Emirates.[160][161][162] He also criticized Obama for seeing allies as "freeloading", saying: "For a sitting US President to see our allies as freeloaders is nuts."[162] He has cited the importance of the United Arab Emirates and Jordan as countries that wanted to help, for example, in filling in the gaps in Afghanistan. He criticized Obama's defense strategy as giving "the perception we're pulling back" from US allies.[163] He stresses the need for the US to bolster its ties with allied intelligence agencies, particularly those of Jordan,Egypt andSaudi Arabia.[164] In 2012, Mattis argued for providing weapons toSyrian rebels as a way to fight back againstIranian proxies in Syria.[165]
Mattis visitedJapan one week after being sworn in as secretary of defense. During a meeting withPrime MinisterShinzō Abe, Mattis emphasized that the US remainscommitted to the mutual defense of Japan and stated, "I want there to be no misunderstanding during the transition in Washington that we stand firmly, 100 percent, shoulder to shoulder with you and the Japanese people."[166] He also reassured Japan that the US would defend the disputedSenkaku Islands controlled by Japan but also claimed by China andTaiwan.[167]
Speaking at a 2015 conference sponsored byThe Heritage Foundation inWashington, D.C., Mattis said he believed thatRussian PresidentVladimir Putin's intent is "to break NATO apart".[168] Mattis has also spoken out against what he perceives as Russia's expansionist or bellicose policies inSyria,Ukraine and theBaltic states.[169] In 2017, Mattis said that the world order is "under the biggest attack since World War II, ... and that is from Russia, from terrorist groups, and with what China is doing in theSouth China Sea.[170]
On February 16, 2017, Mattis said the United States was not currently prepared to collaborate with Russia on military matters, including future anti-ISIL US operations.[9] In August 2017, he said: "Despite Russia's denials, we know they are seeking to redraw international borders by force, undermining the sovereign and free nations of Europe".[171]
On July 1, 2022, he described theRussian invasion of Ukraine as "immoral, the tactically incompetent, operationally stupid and strategically foolish effort". He added thatVladimir Putin "probably thought that the Ukrainian people were going to welcome him."[172]
Mattis and Tillerson with Chinese GeneralFang Fenghui and State CouncilorYang Jiechi, June 2017
Mattis called forfreedom of navigation in the South China Sea and criticized China'sisland-building activities, saying: "The bottom line is... the international waters are international waters."[173]
In 2017, Mattis said that budget cuts would hamper the ability to monitor theeffects of global warming,[13] and noted, "climate change is a challenge that requires a broader, whole-of-government response."[174] He also told senators "climate change is impacting stability in areas of the world where our troops are operating today."[175]
On June 3, 2020, Mattis issued a statement toThe Atlantic in which he criticized President Donald Trump and his policies during theGeorge Floyd protests. He berated Trump for deliberately trying to cause division among the American people and advocating military action to "dominate" the country's protests. "Militarizing our response, as we witnessed in Washington, D.C., sets up a conflict—a false conflict—between the military and civilian society, and diminishes the trust and constitutional relationship between the armed services and the civilian population they support", he wrote. Mattis called for reunification among the people, regardless of the president, to preserve the welfare of society, and its future.[148]
Mattis wrote that Trump was "the first president in my lifetime who does not try to unite the American people—does not even pretend to try. Instead, he tries to divide us". He added that America is "witnessing the consequences of three years without mature leadership". He called for accountability for "those in office who would make a mockery of our Constitution". He concluded, "Only by adopting a new path—which means, in truth, returning to the original path of our founding ideals—will we again be a country admired and respected at home and abroad."[176][148][177][178]
A bachelor for his entire professional career, a now-retired Mattis married physicist and business executive Christina Lomasney[179] in June 2022.[180] He has no children.[2] He had previously proposed to a woman, but the wedding was called off three days before it was to occur, after colleagues talked him out of leaving the Marine Corps for her.[24][181] He was nicknamed "The Warrior Monk" because of his bachelorhood and lifelong devotion to the study of war.[182] An avid reader, he has 7,000 books in his private library,[183] and has recommendedMarcus Aurelius'sMeditations as the one book every American should read.[184]
Mattis is aCatholic, and has been described as "devout"[185] and "committed".[186] During the2003 Iraq invasion, he often prayed with generalJohn F. Kelly on Sundays.[185] The Trump transition team's formal biography of Mattis described him as "the living embodiment of the Marine Corps motto,Semper Fidelis."[186] He has declined when asked by reporters to discuss his faith in public.[187] In a 2003 PBS interview, Mattis recalled how his Marines followed advice from his chaplain on gaining the support of Iraqi citizens:
On the suggestion of my Catholic chaplain the Marines would take chilled drinking water in bottles and walk out amongst the protesters and hand it out. It is just hard to throw a rock at somebody who has given you a cold drink of water and it's 120 degrees outside.[186]
"While occupying key leadership positions within the United States Armed Forces and NATO between 2001 and 2012, General Mattis directly and repeatedly contributed to the Canadian Forces' operational success in Afghanistan. Providing unprecedented access and championing Canadian participation in critical policy and training events, he helped shape Canadian counter-insurgency doctrine. Demonstrating unequivocal support and unwavering commitment to Canada, General Mattis has significantly strengthened Canadian-American relations and has been a critical enabler in both countries' shared achievements in Afghanistan."[188]
Mattis is also known for theInternet meme depicting him as "Saint Mattis of Quantico, Patron Saint of Chaos".[195]
Mattis is commonly "reported on" by the militarysatire websiteDuffel Blog for potentially being fired,[196] winning an "arms race" with Russia,[197] and crossing the Potomac to launch a Roman-stylecoup d'état.[198]
Mattis is an avid reader and releases his reading lists.[199]
