From Stettin in the Baltic to Trieste in the Atlantic, an iron curtain has descended across the Continent. Behind the line lie all the capitals of the ancient states of Central and Eastern Europe... 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 many cases, increasing measure of control from Moscow.
Winston Churchill
