One option being considered is sending European forces to Ukraine but putting the U.S. in charge of their command and control.

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.
