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.

The Communist rulers then propose to substitute a whole new system of thought and control dictated from Communist Party headquarters. They think that a few theorists and rulers know what is best for everyone, and they are determined to drive everyone toward that kind of world. One small country after another has been swallowed up by international Communism. Their freedom is lost. Their national pride is crushed. Their religion is trampled on. Their economies are mere feeders for that of Russia. And if they attempt to assert their tradition of freedom, their people are shot down by the thousands. Witness: Hungary.
As a result, dissatisfaction with capitalism never reached the point at which "proletarians of all countries" felt it necessary to unite to throw off their "chains." That became clear during the Cold War, and it did so largely because western leaders disproved Marx's indictment of capitalism as elevating greed above all else. When set against the perversions of Marxism inflicted by Lenin and Stalin on the Soviet Union and by Mao on China—placing a ruling party and an authoritarian state in control of what was supposed to have been an automatic process of historical evolution—the effect was to discredit communism not just on economic grounds, but also because of its failure to bring about political and social justice. Just as a new world war did not come, so the anticipated world revolution did not arrive. The Cold War had produced yet another historical anachronism.
The cadres of our Party and state are ordinary workers and not overlords sitting on the backs of the people. By taking part in collective productive labour, the cadres maintain extensive, constant and close ties with the working people. This is a major measure of fundamental importance for a socialist system; it helps to overcome bureaucracy and to prevent revisionism and dogmatism.
