The protections that the US and Europe would be able to provide to Ukraine are similar to NATO's collective defense mandate.

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.

Leaders of five European nations, plus the European Commission and NATO, are meeting with presidents Trump and Zelenskyy Aug. 18. Here's who they are.

Kurt Volker is an American former ambassador to NATO and former special representative for Ukraine. Nico Lange is a former chief of staff to the German defence minister.

The Kremlin’s goal is to destabilize Europe, and attacks on infrastructure are a preferred weapon, a new report said.

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

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.

Plans for security guarantees for Ukraine appear to be triggering unease in Moscow, which repeated objections to any role for forces from NATO countries.
