The ideologists of national liberation, those of the world communist movement and those purporting to speak for the revolutionary forces in the Third World, have written ad infinitum on their desired (and inevitable?) goals, and the strategies required to reach them. Mr. MacFarlane has read vast quantities of this nearly indigestible literature, more than enough to make his case, and perhaps he gives ideology more than its due as the mover rather than handmaiden of policy. In any event he does a good job of summarizing the various theories, showing where the ideas of pundits and political leaders in the Third World parallel those of Moscow orthodoxy and where they diverge. It is clear that these Third World movements have found much ideological common ground with the Soviet Union, and very little with America, and that this has given the Soviet Union advantages in the superpower competition in those areas; but the author wisely cautions against concluding that they will therefore win that competition. It should also be noted that in the long run the Soviets are as little tolerant of true nonalignment as was John Foster Dulles.
