Vladimir Putin’s spokesman condemned the arrival of more than 3,000 soldiers in Poland, claiming the move is a threat to Moscow's security. The enforcement, sanctioned by Barack Obama, comes amid growing fears the decision to send US tanks to Eastern borders to deter any Russian threat could in fact trigger an all-out global war.
