This is not quite right. The socialists and communists both believe in the overthrow of capitalism, and may have similar ideas about the endpoint, but their means are different. Socialists are peaceful parliamentarians while communists believe in forceful revolution. They have been even more constrained in the wake of the USSR where Lenin advocated the idea of a vanguard party and due to their initial success, other communists modeled their revolutions on them. The idea Lenin expressed in "State and Revolution" was the idea of the wilting of the state into nothing as it becomes useless without class antagonisms to subdue. If you follow Marx, the only universal, the step that both China and the USSR skipped which might be why they ended up the way they did, was that Socialism is supposed to evolve from advanced capitalism which produces the abundance of tools and facilities that make a new more equitable highly developed civilization possible. The interesting lede here is that the USA is, unlike a poor peasant country, in a state of advanced capitalism and is the most wealthy country in world history. It is also the imperial power that oppresses the rest of the world rather than vice versa. These unique circumstances raise the possibility that Marx's vision might be best fulfilled here, not over there.
