They’re just repeating old Stalinist propaganda.

Moscow, seeing that the Red Referendum manoeuvre had failed, threw all pretence aside and came openly out for letting Hitler in.

On October 14, 1931, Remmele, one of the three official leaders of the Communist Party, with Stalinist effrontery announced the policy in the Reichstag.

“Herr Bruening has put it very plainly; once they (the Fascists) are in power, then the united front of the proletariat will be established and it will make a clean sweep of everything. (Violent applause from the Communists)…We are the victors of the coming day; and the question is no longer one of who shall vanquish whom. This question is already answered. (Applause from the Communists). The question now reads only, ‘At what moment shall we overthrow the bourgeoisie?’…We are not afraid of the Fascist gentlemen. They will shoot their bolt quicker than any other Government. (Right you are! from the Communists) …”

The Fascists, so ran the argument, would introduce inflation, there would be financial chaos, and then the proletarian victory would follow. The speech was printed with a form asking for membership of the party attached and distributed in great numbers all over Germany.

Stalinist parties are led from above. Their leaders get the line and impose it. Disobedience is labelled Trotskyism, Right deviation, and what not, and the dissidents expelled. But the situation in Germany was too tense, and violent protests from the Left Wing caused the policy to be withdrawn. But from that moment it was certain that the Communist Party leadership would never fight, and the “After Hitler, our turn” [25] was the line on which they led the party. The German leadership did not follow blindly. Some of them carried on a ceaseless struggle to the very end. But built on Moscow they faced isolation if they broke with Moscow, and the organisational vice silenced or expelled them. [26]
