Stalin wanted to control the small brothers via an artificial cooperation in Central Europe. The Soviet Union founded the Comecon in 1949 with Bulgaria, Czechoslovakia, Hungary, Poland and Romania. Before Stalin ordered the communist governments of Czechoslovakia, Hungary and Poland to pull out of the Paris Conference on the European Recovery Programme. He wanted to stop the potential relation with the US due to the Marshall aid. So the Comecon was created with a negative point of view of the Big Brother. Stalin wanted of course to have buffer states and not to integrated them. With this act, Stalin thought that he proved that Russia as the Soviet Union was interested in the future of Europe in opposition to the Americans. But the reality was totally different. His goal was to have slaves. The Treaty of Warsaw was a better proof. In 1955 the Soviet Union managed to have in its hand: Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania. With this the slaves were enchained. It was a reaction against the integration of West Germany into NATO.
