"Not all communists, however, fell into that sphere.

He and his partisans, not the Red Army, had driven the Nazis out; unlike any of his other East European counterparts, Tito did not depend upon Stalin's support to remain in power. Efforts to subject him to Cominform orthodoxy caused Tito to bristle, and by the end of June, 1948, he had openly broken with Moscow. Stalin professed not to be worried. "I will shake my little finger, and there will be no more Tito."
