Just to substantiate this:

"As a result of their reorganization on democratic principles, in such former enemy countries as Bulgaria, Finland, Hungary, and Romania regimes have been created which have set themselves the task of strengthening and maintaining friendly relations with the Soviet Union. In the Slavic countries - Poland, Czechoslovakia, and Yugoslavia - liberated by the Red Army or with its help, democratic regimes have also been created and are consolidating which maintain relations with the Soviet Union on the basis of friendship and mutual aid agreements."

In Romania the "democratic regime" had received something like 3% of the votes at its inter-war peak and had later been banned for subversive activities sponsored by the Soviets.

There were solid reasons those "former enemies" were enemies.
