The "Iron Curtain Speech" was delivered by Winston Churchill to emphasize the need for the US and Britain to act as peacekeepers for the threat imposed by the USSR. He implored on the two nations to spearhead the need to maintain peace against the power of the communist USSR.
In his now-famous speech, former British Prime Minister Churchill stated <em>"From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent."</em> He also went on to express his belief that the Soviet Union's communist stance and desire to expand will <em>"cause new serious difficulties in the British and American zones."</em> He then appealed for <em>"[T]he safety of the world [that] requires a new unity in Europe, from which no nation should be permanently outcast."</em>
