The key point I was trying to make is that the current war does not depend on conscription. We have enough incentive in terms of pay and benifit and enough people with no other skills that we do not need conscription, so the kids have no reason to protest like the did in Vietnam.
The other point is, and I am amused that some silly person spent an hour trying to retcon history(like Boehner is trying to do with the government shut down and the impeachment threats(so sarah palin never suggested that we impech obama, only those in the administration) is that those who were directly impacted by his action or indirectly impacted by those who were supporters did not have any recourse. It is like the no fly list now, except the no fly list is secret and does not seem to focus on certain famous US citizens whom the McCarthy type people did like.
As far as the various wars of the Veitnam era an the various wars of current Iraq era, they were political, religious, and economic factors in both. Obviously the former was a religious type fanaticism against communism, while the later is a political fanaticism against Islam. The former was to protect us against a Russian aggression through Cuba, while the later to protect us against a radical 'Muslim' aggression through terrorism. In both cases free exploitation of resources, including oil, was a proximate factor. In either case proxy wars are fought. Vietnam instead of China, Iraq instead of Afghanistan(I know we are now in Afghanistan, but the horses were already out, so to speak).
