Special U.S. envoy Steve Witkoff says Russian leader Vladimir Putin agreed to allow the U.S. and Europe to offer Ukraine a security guarantee resembling NATO's collective defense mandate.

The president praised his guests at this week’s meeting, a change in tone that follows big concessions from Europe and careful observations of the way he operates.

On Aug. 18, 2025, Trump met European, EU and NATO leaders at the White House to discuss the ongoing war in Ukraine.

The leaders of Germany, France, Britain and other supporters of Ukraine have come together in exceptional ways to help sway the U.S. president.

U.S. President Donald Trump told President Volodymyr Zelenskiy on Monday that the United States would help guarantee Ukraine's security in any deal to end Russia's war there, though the extent of any assistance was not immediately clear.

Donald Trump said the US would help arrange European security guarantees for Ukraine if peace could be agreed with Russia, as he pledged to set up a meeting between Volodymyr Zelenskyy and Vladimir Putin.
