Communist parties do not "await" revolution. When you only wait for revolution, you will keep doing that forever. Communist parties work towards forcing a revolution (to the best of their abilities), by bringing about the conditions under which revolutions are successful, and this means organising, building a public presence, teaching theory, and supporting the actions of the revolutionary element of society, such as unionised labour, student groups, and the proletariat in industry and service economy.
They also protest against the police state and the war machine, engage in antifascist activism, and try mitigating the most immediate environmental and psychological effects of capitalism while they are unfolding.
