NATO ground troops in Ukraine? Another member state is open. According to Czech media reports, Petr Pavel does not rule out sending Western troops to Ukraine - although not to fight against Russia, but rather for training purposes.

“Although Ukraine was attacked, it is still a sovereign country,” Pavel said, adding that such a training mission would not violate international rules. It makes no difference whether Ukrainian soldiers are trained by Western allies abroad or in Ukraine itself, Pavel continued. Europe as a whole must play a larger role in deterrence.
