To summarize, draft resistance can make use of the inegalitarian nature of American society as a technique for increasing the cost of American aggression, and it threatens values that are important to those in a decision-making position.

The Vietnamese see their history as an unending series of struggles of resistance to aggression, by the Chinese, the Mongols, the Japanese, the French, and now the Americans.

There's very little dislike of Americans in the world, shown by repeated polls, and the dissatisfaction - that is, the hatred and the anger - they come from acceptance of American values, not a rejection of them, and recognition that they're rejected by the U.S. government and by U.S. elites, which does lead to hatred and anger.

American society is still puritanical.

My own feeling is that one should refuse to participate in any activity that implements American aggression - thus tax refusal, draft refusal, avoidance of work that can be used by the agencies of militarism and repression, all seem to me essential.
