The United States joined Russia to vote against a UN General Assembly resolution condemning Russia’s war against Ukraine Monday in a stunning shift from years of US policy.

Washington’s shift on the Ukraine war marks a major break with European allies and comes as the Trump administration aims to repair relations with Russia.

After 3 years of brutal fighting in Eastern Europe, many would welcome an end to Russia's full-scale invasion, but a peace deal that would satisfy all remained elusive.

Europeans are debating additional funding and contemplating troops in Ukraine as American support appears ever more at risk.

NBC News’ Richard Engel, Former Deputy Assistant Secretary of Defense Evelyn Farkas, and Former U.S. Ambassador to Russia Michael McFaul join Katy Tur to express concerns about Trump’s deference towards Russia.

Whether they do so will likely determine the extent of Europe’s role in shaping a peaceful Ukraine. European diplomats privately say Trump’s broadside against Ukrainian President Volodymyr Zelenskiy last week—when he falsely said Ukraine started the war with Russia and labeled its leader a dictator—was disgraceful and reflected Russian disinformation.
