> the reasons we don't are ethical/economical/politcal The US's history with war is far from any of those reasons. Ethics is one of the least of politicians concern. The main reason why the US hasn't invaded a big country yet is because the world is divided in 2, and invasion would mean the end of the world. Iraq, Afghanistan and Yemen (recent ones) would beg to differ on the US's very ethical wars.
