THE PASSING of Marxism-Leninism first from China and then from the Soviet Union will mean its death as a living ideology of world historical significance. For while there may be some isolated true believers left in places like Managua, Pyongyang, or Cambridge, Massachusetts, the fact that there is not a single large state in which it is a going concern undermines completely its pretensions to being in the vanguard of human history. And the death of this ideology means the growing "Common Marketization" of international relations, and the diminution of the likelihood of large-scale conflict between states.
