True.

Explanation:

NATO was created in 1949 as a response to a perceived Soviet security threat to Western Europe. In those times, some in the West feared that the Red Army could invade some countries to impose a communist regime. So, the US and its allies created NATO. The Warsaw Pact was the political and military alliance of communist states in Europe. It was created in 1955 after NATO took the decision to include Western Germany as a member.
