The third and most important reason why I think Vietnam is relevant to the situation in Iraq is because the Americans found themselves in the unfortunate position where they were beating down on the weak. To quote Dayan: “any comparison between the two armies… was astonishing. On the one hand there was the American Army, complete with helicopters, an air force, armor, electronic communications, artillery, and mind-boggling riches; to say nothing of ammunition, fuel, spare parts, and equipment of all kinds. On the other there were the [North Vietnamese troops] who had been walking on foot for four months, carrying some artillery rounds on their backs and using a tin spoon to eat a little ground rice from a tin plate.”
That, of course, was precisely the problem. In private life, an adult who keeps beating down on a five year old – even such a one as originally attacked him with a knife – will be perceived as committing a crime; therefore he will lose the support of bystanders and end up by being arrested, tried and convicted. In international life, an armed force that keeps beating down on a weaker opponent will be seen as committing a series of crimes; therefore it will end up by losing the support of its allies, its own people, and its own troops. Depending on the quality of the forces – whether they are draftees or professionals, the effectiveness of the propaganda machine, the nature of the political process, and so on – things may happen quickly or take a long time to mature. However, the outcome is always the same. He (or she) who does not understand this does not understand anything about war; or, indeed, human nature.
