The US hardly has a stirling post-WW2 record:
- Korea, stalemate
- Vietnam, disaster
- Iraq, so far, disaster
All of these have proven enormously expensive, and by the way, France's getting her ass kicked in Vietnam was, at least, paid for by the USA.
Grenada, Gulf War and Panama all successful military operations. Also the US never lost a battle in Vietnam, and had it not been for the civilian element at home would have been a military success.
