In May 1955, Western allies signed a series of agreements in Paris which made West Germany a member of NATO and allowed the country to have its own armed forces again. There were strict limits on the new German army, but to the USSR, USA rearming the enemy who had caused so much turmoil during WW2 was worrying. In response, Khrushchev created the Warsaw Pact which was a military alliance similar to NATO. The members would defend each other if one was attacked. It included all of the Communist EE countries except Yugoslavia, but it was dominated by the USSR.
