US may provide air support for Ukraine under peace deal - Trump

"When it comes to security, (European allies) are willing to put people on the ground. We're willing to help them with things, especially, probably, by air," Trump said, stressing that no U.S. troops would be deployed on Ukrainian soil. BBC reported.

Kyiv has long insisted on binding security guarantees from its allies to prevent Moscow from invading again after a ceasefire. 

Trump initially dismissed such guarantees as Europe's responsibility, but has recently shifted his position.

White House Press Secretary Karoline Leavitt said on Aug. 19 that U.S. air support remains "an option and a possibility." She did not specify what form it could take, though air support could involve missile defense systems or a no-fly zone.
