After the end of the First World War in countries such as Germany and Hungary, the revolutionary movement led to the creation of the Soviet republics. How can you explain their defeat?

After the end of the First World War in the countries that were part of the Kaiser coalition, in particular in Germany and Austria-Hungary, after the defeat there were strong socialist movements that led to the revolution. The revolution was victorious in Germany and Hungary, Austria seceded and became an independent state.
