"The Communist Party is the sworn inveterate enemy of the Socialist and Democratic Parties. When it associates with them, it does so as a preliminary to destroying them. There is an old German aphorism which says: "To cast an enemy out it is first necessary to embrace him." That is what the Communists mean when they ask for co-operation and alliance with the Socialists... The Communist does not look upon a Socialist as an ally in a common cause. He looks upon him as a dupe, as a temporary convenience, and as something to be thrust ruthlessly to one side when he has served his purpose."
