A communist revolution and takeover of Germany was a very real fear of the British, French, and Americans when they were drawing up the Treaty of Versailles, almost as much as a rearmed and resurgent Germany. The Soviets did not have a common border with Germany after WWI, and there was no Warsaw Pact yet. The creation of the new states of central and eastern Europe provided what Georges Clemenceau called a "cordon sanitaire" to contain communism within the Soviet borders. Moreover, the French had defense treaties with Poland and Czechoslovakia in the event of Soviet or German aggression. To intervene directly, the Soviets would have had to cross at least those two countries, which would have in theory drawn in the French and possibly the British.
