Exclusive: Biden tells Muir US weapons will not be used to strike Moscow, Kremlin

Weapons should be used to strike whatever targets will help bring the speediest collapse of the Russian invasion, up to and including targeting Putin.

Russia has shown no restraint in trying to hit Kyiv or in trying to kill president Zelensky, it does not help Ukraine or the west in general to tie the Ukrainian military's arm behind their back.

Except at hospitals and schools at Gaza.
