In 1997, he moved to Yale University to become the Lovett Professor of Military and Naval History. In the 2000–01 academic year, Gaddis was the George Eastman Professor at Oxford, the second scholar (afterRobin Winks) to have the honor of being both Eastman and Harmsworth professor.[11][12] He sits on the advisory committee of theWilson Center'sCold War International History Project,[13] which he helped establish in 1991.[14] Gaddis is also known for his close relationship with the lateGeorge Kennan and his wife, whom Gaddis described as "my companions".[15]
Gaddis is a well-known historian for his writing about the Cold War.[16] Perhaps his most famous work isStrategies of Containment (1982; rev. 2005),[17] which analyzes the theory and practice ofcontainment that was employed against the Soviet Union by Cold War American presidents. His1983 distillation of post-revisionist scholarship also guided Cold War research.[18]
We Now Know (1997) presented an analysis of the Cold War through theCuban Missile Crisis that incorporated new archival evidence from the Soviet bloc.[19][20] It is one of the first attempts to write the Cold War's history after it ended.[21]
The Cold War (2005) is an examination of the history and effects of the Cold War in a more removed context,[22][23] and won Gaddis the 2006Harry S. Truman Book Prize.[24] Critics were less impressed, withTony Judt summarising the book as "a history of America's cold war: as seen from America, as experienced in America, and told in a way most agreeable to many American readers,"[25] andDavid S. Painter writing that it was a "carefully crafted defense of US policy and policymakers" that was "not comprehensive."[16]
John Nagl described Gaddis's 2018 bookOn Grand Strategy as "a book that should be read by every American leader or would-be leader".[26]
Gaddis is known for arguing thatSoviet leaderJoseph Stalin's personality and role in history constituted one of the most important causes of the Cold War. Within the field of U.S. diplomatic history, he was originally most associated with the concept ofpost-revisionism, the idea of moving past the revisionist and orthodox interpretations of the origins of the Cold War to embrace what were (in the 1970s) interpretations based upon the then-growing availability of government documents from the United States, Great Britain and other western government archives.[citation needed] Due to his growing focus on Stalin and leanings toward US nationalism, Gaddis is now widely seen as moreorthodox than post-revisionist.[27][28] Revisionist historianBruce Cumings had a debate with Gaddis in the 1990s, in which Cumings criticized Gaddis as moralistic and lacking in objectivity.[29]
During the US invasion of Iraq, Gaddis argued: "The world now must be made safe for democracy, and this is no longer just an idealistic issue; it's an issue of our own safety."[30] During theUnited States occupation of Iraq, Gaddis asserted that Bush had established America "as amore powerful and purposeful actor within the international system than it had been on September 11, 2001." HistorianJames Chace argues that Gaddis supports an "informal imperial policy abroad."[31] Gaddis believes thatpreventive war is a constructive part of American tradition, and that there is no meaningful difference between preventive andpre-emptive war.[32]
About the FirstTrump presidency he said, "We may have been overdue for some reconsideration of the whole political system. There are times when the vision is not going to come from within the system and the vision is going to come from outside the system. And maybe this is one of those times."[33]
Gaddis was born inCotulla,Texas, the son of Harry Passmore Gaddis and his wife Isabel Florence (Maltsberger) Gaddis.[34][35] He is close to PresidentGeorge W. Bush, making suggestions to his speech writers,[36] and has been described as an "overt admirer" of the 43rd President.[37] After leaving office, Bush took up painting as a hobby at Gaddis's recommendation.[38] Gaddis is a fellow of theAmerican Academy of Arts and Sciences.[39][40]
