Just one obvious rebuttal regarding the examples of Iraq/Afghan insurgent groups holding up well against the US government: those guys are still up against a government that ostensibly tries to uphold humanitarian ideals. I'm talking about rising up against a government where those ideals have been severely compromised (to, let's say, Stalin era USSR or present day North Korea). I doubt a government like that would mind blowing up a few women and children to get at the meat.

Say you're cooped up somewhere so that you're hard to bomb and whatnot. If I were a supreme ruler that didn't give a rat's ass about international law or collateral damage, I'd probably use some chemical/biological weapon to just wipe out the area. How are you going to fight against a government like that? And hypothetically, if the US had decided to just nuke or chemically treat Iraq, the insurgency wouldn't have stood a chance (and apparently a strategy that some morally bankrupt Americans seem to share. It's a reprehensible refrain I've often heard repeated by guys and gals on the street being interviewed on news channels in the US).

Anyway, why are you people living like it's the end of times or something. You remind me of millenarians. Read some history. Be glad you have running water and a toilet in your house. And all your teeth.
