Winning Trump's favor is one thing. Keeping it is another.

Just four months after their tense Oval Office meeting on February 28, 2025, Donald Trump welcomed Volodymyr Zelensky at the NATO summit in Ankara with a noticeably warmer tone. For Ukraine, that's an encouraging shift—but hardly a guarantee of lasting American support.

Former Ukrainian Foreign Minister Dmytro Kuleba knows that better than most. He spent four and a half years leading Ukraine's diplomacy, including the first years of Russia's full-scale invasion, working to keep Washington and America's allies united behind Kyiv.

On GZERO World, Kuleba joins Ian Bremmer from Kyiv to discuss why Ukraine is in a stronger military and diplomatic position than it has been in years, whether that momentum can finally be translated into a lasting advantage, and why the real challenge isn't winning President Trump's support—it's keeping it. They also examine what a stronger Ukraine means for Vladimir Putin, whether mounting pressure could bring the war closer to an end, or simply make the Kremlin more dangerous.
