The Hidden Past and Uncertain Future of the U.S. and Ukraine with Celeste Wallander

Under the Trump administration, U.S. support for Ukraine is no longer guaranteed. President Trump's pause on aid and intelligence to Ukraine in March may have been brief, but it sent a clear message to Europe and Ukraine that the U.S. may no longer be a reliable partner for Ukraine. A reduction or end to U.S. support for Ukraine could have a significant impact on the conflict dynamics in Ukraine and present a challenge for European allies as to whether they can step up and fill the gap.

Celeste Wallander joins the podcast to provide a firsthand account of the evolution of U.S. assistance to Ukraine and to discuss how a united Europe can help Kyiv keep up the fight.

Celeste Wallander was the assistant secretary of defense for International Security Affairs and is a adjunct senior fellow at CNAS.
