As winter approaches and territorial changes along the frontlines in Ukraine continue to be minimal, the realization is setting in that a long war likely lies ahead. To continue to defend itself against Russia’s aggression in the months and years to come, Kyiv will need the full support of its Western backers. Yet continued aid from the United States—Ukraine’s largest provider of weapons by far—is looking increasingly doubtful. To unpack the political reality around Ukraine support in the United States and the likely implications for Kyiv’s war effort, Ivo Daalder joins Andrea Kendall-Taylor and Jim Townsend on this week’s episode of Brussels Sprouts.

Ivo Daalder is President of the Chicago Council on Global Affairs. From 2009-2013, he served as the United States’ Ambassador to NATO.
