Trump has horrified European allies with his attacks on Volodymyr Zelenskyy and what critics say is a soft take on Vladimir Putin.

Russian President Vladimir Putin said on Monday that Russia was not opposed to Europe's involvement in Russia-U.S. peace talks aimed at settling the conflict in Ukraine, but noted that Brussels had long rejected any dialogue with Moscow.

Trump refused to call Vladimir Putin a dictator, as he has described Ukraine’s president, Volodymyr Zelensky, and falsely claimed that the U.S. had spent three times as much as Europe on the war. He demanded that Ukraine sign over hundreds of billions of dollars in revenue from natural resources to the U.S., without mentioning Russian concessions.
