European leaders back Ukraine after U.S. tensions

European leaders are showing strong support for Ukraine's President Volodymyr Zelenskyy after a tense meeting with U.S. President Donald Trump. Zelenskyy left the White House without signing a mineral deal, following accusations from Trump that he was ungrateful and unprepared for peace with Russia. In response, European leaders, including British Prime Minister Keir Starmer and Polish Prime Minister Donald Tusk, expressed their backing for Ukraine. A summit in London on Sunday will focus on strengthening support for Ukraine and increasing European defense cooperation amid concerns about U.S. commitment to NATO. Trump's recent shift in U.S. policy, seeking a deal with Russia while sidelining Ukraine, has alarmed European allies. Tensions escalated during the White House meeting, where Trump and Vice President JD Vance confronted Zelenskyy, leading to a public fallout.
