The British were able to control vast swaths of the world with minimal military power. They fought smart.
I remember watching Restrepo and other similar documentaries. I come from a tribal culture too; and there were several instances where I could clearly see how the Americans were making a mistake in their dealing with the locals. Those people have been living and dying by their tribal codes for millennia, and "democracy" and "freedom" means nothing to them.
Minor nitpick: it was GHW Bush who committed US troops to Somalia, just as he was leaving office, in December 1992; a nice welcoming present for Clinton.
Edited: It was pappy Bush, not Dubya. Thanks @theorique :)
