ABSTRACT
The moderation of Soviet policy, the loosening of the Soviet bloc in Eastern Europe, the disruption of the Sino-Soviet bloc, the frustration of Communist China's expansionist ambition, and the failure of either of the principal Communist states to extend their domain by exploiting revolution in the backward areas, these developments fulfill the most critical objectives of the policy of containment enunciated twenty years ago. The policy-makers in Washington were probably not basically motivated by the crusading spirit, but it was reflected in the way in which the doctrine of containment was generally applied. American diplomacy succeeded in Europe not only because it contained Communism, but because it promoted economic progress and human liberty. The Bay of Pigs landing was a twofold failure, both political and moral; the intervention in Santo Domingo was both a military and a short-term political success, but the moral cost probably outweighed the benefit.
