The US military, large and well armed as it is, has very little chance in occupying and subduing our population. Yeah, they can kill a bunch of people, but the most quoted ratio for soldiers-to-population in an occupation is 20 per 1,000 (earlier phases are said to require even more). With a population of about 300M, I think that works out to about 6 million soldiers needed. We don't have that many people in our military, not close.
"Supply Lines"? I'm not even sure the "lines" part would be the military's biggest problem. The military gets it's supplies from citizens in the first place. How's that gonna work if we're fighting each other?
As hard as it is to occupy place like Afganistan or Iraq, compare their populations to ours: we are far more knowlegeable with far more resources. We have all kinds of engineers, electricians, scientists and tradesmen. We have thousands of machine shops all across this country. We have millions of tons of fertilizer and diesel fuel etc. Jeeez, I can buy high quality gun powder in 20lbs kegs at the local gun store about 10 minutes from my office.
And BoberFett, I was thinking about this in that postal service thread yesterday about how robust (or not) our technology is (your floating chair anology) - I saw an article in Popular Mechanics a few years about creating a large EMP. They published the basic plan for creating a device for about $3k IIRC, and it required at least a prop plane to deploy, that would supposedly creating an EMP large enough to knock out most circuitry in the USA. Deploy a couple of those and fighter jets might be turned into big paper weights. (In yesterday's thread I was thinking how'd we lose call phones, PC's, receivers for satelitte TV etc - drastically limited communication capability and commerce etc).
