KYIV, Ukraine (AP) — As Ukraine approached the three-year mark of Russia’s full-scale invasion, the country’s hoped-for path to a favorable and lasting peace has been upended in a matter of days by the administration of U.S. President Donald Trump. Kyiv had benefited from years of staunch support by its allies in the United States and Europe which had provided crucial military and financial support to help defend against Moscow’s grinding incursions. But when Trump held a lengthy phone call with Russian President Vladimir Putin last week — undoing years of U.S. policy to isolate the Russian leader — it was taken as a signal in Kyiv and other European capitals that their alliance to contain Moscow was fraying.
