The fact that the communist system was accepted and imposed in so many countries after The Second World War is not due to local beliefs. The ideology had been known in the South-Eastern countries since the end of the First World War. Nevertheless, it did not appeal to many people. Contrary, it had more enemies than supporters. Moreover, is some cases, like Romania's, the communist activists were acting against the law. Additionally, even the few intellectuals who had been attracted by its ideas were against the cruelty of the Soviet authorities. So, there had to be other reasons for the massive export of communism in the Eastern states.
The high speed that characterized the expansion of the Russian domination proved that "Stalin had a strategy for these states". He put this plan into practice as soon as the Red Army reached that place. More than that, his own words sustain this thesis: "This war is not as in the past. Whoever occupies a territory also imposes on it his own social system. Everyone imposes his social system as far as his army goes. There's no other way". The Bolshevism was an ideology imposed in this area because, whatever the national circumstances, the political and cultural customs, the communism was successful up to where the Red Army managed to arrive. Defeated countries, like Romania and Germany had the same faith like the winning Poland and Czechoslovakia. The system was winning.
The worst problems of the communist regime in S-E Europe are related to the Western state's response to Russia's intention of imposing its political system by force and to how communism managed to prolong its life so long in spite of the local ideas and level of development, especially when it barely had adepts in the communist parties in different countries. At the end of The Second World War, there were different opinions on how to organize the post-war world. The intensive offensive of the Red Army in 1944 amazed both Churchill and Roosvelt, who were forced to accept this situation by means of the Yalta Conference in February 1945. This meant the necessity to create a security area in the Western border of URSS, made of democratic states. This attitude of the greatest Western powers can only be justified by their own interests, in other words by the fact that they could not afford a military fight against Stalin on this matter. Although the democrat leaders did not agree with the communists, they had to accept the fact that they forced people to join them by using the army.
