But this wasn't unrestrained war, it was nation building, and we are no good at trying to be imperialists, yet we try, and its sad, and I think the country will for the foreseeable future have learned from these mistakes, but Iraq and Afghanistan were not unrestrained wars, they were attempts at nation building, and we failed for so many reasons.
If they were more conventional, say like the Gulf War was, it would have been over in days, weeks maybe.
Completely unrestrained? I don't think we'd be talking about Iraq and Afghanistan as current countries.
