Not even two months into his second term, U.S. President Donald Trump is reshaping U.S.-Russian relations at a critical juncture for the war in Ukraine. As Russian President Vladimir Putin presses his advantage on the battlefield, Trump’s admiration for the Russian leader, and his push for warmer relations with Moscow, is raising alarms across European capitals—in Kyiv most of all. Fiona Hill spent years studying Putin and Russia as a scholar and U.S. intelligence official before serving, in the first Trump administration, as senior director for European and Russian affairs on the National Security Council. She became a household name during Trump’s first impeachment, when her testimony provided crucial insights into Trump’s dynamic with Putin and his early interactions with Ukrainian President Volodymyr Zelensky. Today, she is a senior fellow at the Center on the United States and Europe at the Brookings Institution and serves as Chancellor of Durham University. Hill spoke with editor Dan Kurtz-Phelan on the morning of Tuesday, March 11, about Trump’s relationship with Putin, the prospects for peace in Ukraine, and European security in an age of American retreat. Later that afternoon, U.S. and Ukrainian officials unveiled a tentative agreement for a 30-day cease-fire—putting the ball in Putin’s court.
