<P> From Stettin in the Baltic to Trieste in the Adriatic an iron curtain has descended across the Continent . Behind that line lie all the capitals of the ancient states of Central and Eastern Europe . Warsaw, Berlin, Prague, Vienna, Budapest, Belgrade, Bucharest and Sofia; all these famous cities and the populations around them lie in what I must call the Soviet sphere, and all are subject, in one form or another, not only to Soviet influence but to a very high and in some cases increasing measure of control from Moscow . </P> <P> Much of the Western public still regarded the Soviet Union as a close ally in the context of the recent defeat of Nazi Germany and of Japan . Although not well received at the time, the phrase iron curtain gained popularity as a shorthand reference to the division of Europe as the Cold War strengthened . The Iron Curtain served to keep people in and information out, and people throughout the West eventually came to accept and use the metaphor . </P> <P> Churchill's "Sinews of Peace" address was to strongly criticise the Soviet Union's exclusive and secretive tension policies along with the Eastern Europe's state form, Police State (Polizeistaat). He expressed the Allied Nations' distrust of the Soviet Union after the World War II . In September that year, US - Soviet Union cooperation collapsed due to the US disavowal of the Soviet Union's opinion on the German problem in the Stuttgart Council, and then followed the announcement by US President, Harry S. Truman, of a hard line anti-Soviet, anticommunist policy . After that the phrase became more widely used as anti-Soviet term in the West . </P> <P> In addition, Churchill mentioned in his speech that regions under the Soviet Union's control were expanding their leverage and power without any restriction . He asserted that in order to put a brake on this ongoing phenomenon, the commanding force of and strong unity between the UK and the US was necessary . </P>
