The condition for the state withering away is the end of class conflict. The state is merely an instrument of class conflict, through which one class exerts its will and dominance over the other. So long as there is a capitalist class anywhere in the world that is organized militarily and is capable of re-asserting itself as a dominant geopolitical force, then the conditions that necessitate a proletarian state still exist and the withering away of that state would be premature.
