That's interesting. That of course pre-supposes that a significant number of military personnel would desert their posts. But definitely some would. Perhaps the same number as those who would get the "Resistance" label in the thread with the test regarding Nazism. But the brass would stay in their positions I think. It also pre-supposes that a significant number of Americans would actually want to overthrow the government. Based on what I read in forums and in the media I don't think there is a significant number who would do so, certainly not sufficient to take on the military power of the government.
Depends on what the issues is. If the guv'mint attempts a direct attack on The Constitution, as in trying to take away our guns, many would fight. As a conventional attack on the military would be out of the question, guerilla tactics would prevail. Even on a one to one ratio the results would be very bad for the military and guv’mint, and they would sustain much more damage than the pacifist public would be able to take. Look at the pressure the pacifists are putting on Bush for 3500 dead soldiers in Iraq. In reality the number of civilian guns would far outweigh the number of military and police.
