In a lengthy interview on 24 March 2022 Kuleba called Russian presidentVladimir Putin a "war criminal". According to him, the Russians had already usedwhite phosphorus munitions andcluster bombs.[12] On 10 May 2022, Kuleba said that "In the first months" of the2022 Russian invasion of Ukraine "the victory for us looked like withdrawal of Russian forces to the positions they occupied before February 24 and payment for inflicted damage. Now if we are strong enough on the military front and we win the battle for Donbas, which will be crucial for the following dynamics of the war, of course the victory for us in this war will be the liberation of the rest of our territories", includingDonbas andCrimea.[13]
After Putin announced apartial mobilization of Russia's armed forces and referenced a potential use ofnuclear weapons, Kuleba said that "Putin has shown utter disrespect to China, India, Mexico, Turkey, other Asian, African, Middle Eastern, Latin American nations which have called for diplomacy and an end to Russia's war on Ukraine."[14] On 10 October 2022, he urged African states to abandon theirneutrality and condemn Russia's invasion of Ukraine.[15] He called Putin a "terrorist" whose "only tactic is terror on peaceful Ukrainian cities."[16] On 28 October 2022, he demanded the immediate cessation of the supply ofIranian weapons to Russia, including Iraniankamikaze drones.[17] On 12 November 2022, he urgedASEAN countries to abandon their neutrality and support Ukraine.[18]
In a December 2022 interview with the Associated Press, Kuleba called for a February 2023 peace summit at theUnited Nations mediated by secretary-generalAntónio Guterres, only inviting Russia if it faces an international court for war crimes.[19] In another December interview, he predicted that:[20]
After this war we will be full members of both the EU and NATO, and guarantors of global food security. We will be an integral and indispensable part of the West. The West is not a geographical notion; it's a political one. And if you share the same principles and values, irrespective of your geography, you belong to the West.
In December 2022 Kuleba criticized India for buying cheapRussian oil.[21] On 29 December 2022, following thestrikes against Ukrainian infrastructure, Kuleba tweeted, "There can be no 'neutrality' in the face of such mass war crimes. Pretending to be 'neutral' equals taking Russia's side."[22]
As the one-year anniversary of the invasion drew near, Kuleba went to the US and spoke toHarvard University students,[23][24]while he quarterbacked a number of diplomatic initiatives at the United Nations in New York, for example passing Resolution ES-11/7 of theEleventh emergency special session of the United Nations General Assembly on 23 February and one day later the 9269th meeting of theUnited Nations Security Council addressed the "Maintenance of peace and security of Ukraine", during which a roll call of friends and allies spoke in favour of Ukraine for over three hours.[25][26]

In March 2023, Kuleba said that China "will not allow Russia to collapse" but "they need a weak Russia to make concessions to China, to provide their resources."[27]
On 16 May 2023, South African PresidentCyril Ramaphosa announced that the leaders of African countries came up with a new initiative forpeace in Ukraine.[28] Both Russia and Ukraine welcomed the African leaders' mission, but Kuleba warned that "Any peace initiative should respect the territorial integrity of Ukraine, it should not imply, even in-between the lines, any cessation of Ukrainian territory to Russia. Second, any peace plan should not lead to the freezing of the conflict."[29]

In July 2023 when Ukrainian four-time individual world sabre championOlga Kharlan was disqualified at theWorld Fencing Championships for not shaking the hand of her defeated Russian opponent, though she instead offered a tapping of blades in acknowledgement, Kuleba voiced support for Kharlan.[30][31] He wrote on social media: "I urge [Fédération Internationale d'Escrime] to restore Kharlan's rights and allow her to compete."[32]
We see that the actual Dynamics in engaging countries from all over the world into the Ukrainian plan is very positive and I think we are setting a precedent here where the terms of peace are being defined by a country whose peace was broken by an Invader it's not the Invader who imposes his peace terms on the victim it's not the third party that is proposing a compromise solution in a form of Peace terms it's us the country that is fighting back that defines the rules of peace and I think it's quite a remarkable moment in human history and in the history of wars and diplomacy.
One of the 10 points in this plan is accountability and accountability implies the tribunal and paying for the damage inflicted and the most important part of this peace plan is of course restoring territorial Integrity of Ukraine so when we hear arguments coming from someexperts or thinkers that maybe it's worth freezing the conflict our response is you know we need frozen assets not frozen conflict.
This is the way forward: to send a clear message to everyone in the world that if you dare to break rules you're going to pay. If we don't send that message if we don't make it very clear the number of conflicts--Interstate conflicts--and tensions across the globe will grow and I think this is and the price of fixing them will be much higher than the price of helping Ukraine. I think this is one of the motivations that brings all these countries at the table because they realize the consequences of not participating in an effort to restore peace on just terms.
