Cowboys and Aliens

I see the movie Cowboys and Aliens is out on DVD. Cowboys in the old west fight off an alien invasion.

It's pretty much what's happening right now in Afghanistan, but the Americans are the aliens using weapons against the Afghan people that they have no defense against. Drones called "Predators" and "Reapers" firing missiles at people. Some Afghan children who were attacked and badly injured by American helicopters while they were out gathering firewood described being "hunted" by the faceless vermin in the helicopters.

I haven't seen the movie, but, since it was set in the 1870s, I assume the cowboys won.
