Correct me if I am wrong but they have also lost every conflict they have been in where they had to be an occupying force. The largest military spending in the world and so far they have failed vs:
Korea Vietnam Afghanistan Iran Iraq Niger 1/2 of Russia (the civil war in 1918) Indonesia Laos Cuba (well that one is more on the CIA) Cambodia Somalia
I am sure I am missing some, but its wild to go though the many many conflicts the us has been involved in.
