A troop of European leaders will support Volodymyr Zelenskyy on Monday as the American president fueled new alarm among Ukraine's allies after his summit with Vladimir Putin.

President Volodymyr Zelensky and European leaders will aim to defend Ukraine’s position in talks after President Trump aligned more closely with Russia. Hours before the meeting, Russia hit Ukraine with a deadly strike.

Hungary accused Ukraine of an "outrageous and unacceptable" attack that disabled a Russian oil pipeline supplying the NATO ally—and fired a warning to Kyiv about its reliance on Hungarian electricity supplies. Newsweek has contacted the Ukrainian foreign ministry for comment.

European leaders may have rushed to Washington ostensibly to throw a protective arm around President Zelensky and head off any repeat of February's Oval Office bust-up. But their real aim is to stop US President Donald Trump threatening long-term European security after his abrupt change of course over how best to end the war in Ukraine.

Ukraine’s Donbas, consisting of Donetsk and Luhansk, is at the heart of Moscow’s goals. An industrial powerhouse in the Soviet era, it also has rich farmland, important rivers and a coastline on the Sea of Azov.

Russia’s illegal seizure of the Crimean Peninsula from Ukraine in March 2014 was quick and bloodless, and it sent Moscow’s relations with the West into a downward spiral unseen since the Cold War.

Sir Keir's role at the White House is likely to rely on the rarity of his strong relationships with both Trump and Zelensky.

MSNBC's Joe Scarborough on Monday morning stated two obvious facts about the Ukraine War that get lost in the commentary sometimes: JOE SCARBOROUGH: Let's underline two things here--just again, to set expectations.
