What: The Warsaw Pact Treaty, a treaty of friendship, cooperation, and mutual assistance.
When: May 14, 1955.
Where: Warsaw, Poland.
Why: The historical circumstances that led to the writing of the Warsaw Pact Treaty were the growing tensions and divisions in Europe during the early years of the Cold War. The Treaty was a response to the establishment of the North Atlantic Treaty Organization (NATO) in 1949 and sought to create a unified defense alliance among the communist states in Eastern Europe. The Treaty aimed to counter the perceived threat of NATO and to maintain the Soviet Union's influence over its satellite states. It also aimed to ensure collective defense and provide mutual assistance in the event of an armed attack on any of the member states, as well as to strengthen international peace and security according to the principles of the United Nations Charter. rephrase the "why" into an only 30 word count
