Establishing the proletariat as the ruling class after a socialist revolution in order to create a transition to communism. This strategy includes developing democracy insofar as appropriate and suppressing – by force when necessary – resistance by exploiting classes or any other elements hostile to the new regime.
In traditional Marxist-Leninist thinking, this transition period is the time for a new regime to restructure society along socialist lines.
Any revolutionary scheme which envisions an idealized end-point is difficult to apply to social reality.
