@aeva the US has been pretty good at the war part of war and godawful at the nation building part after from what I've seen of recent history.
Desert Storm 1 and the war(s) in the Balkans went about as well as can be expected for the areas from what I can tell. Iraq 2 became a disaster pretty much immediately after the us "won" and drove Saddam's government from power. It's pretty clear that the powers that be were completely blinded by ideology and naked greed.
