Yeah, the Europeans were doing great in WWII until the US showed up.
Vietnam is a loss. Iraq is a mess, but isn't really a war or a loss. It's just... bad. But War of 1812, Spanish-American, Mexican-American, WWI, WWII. Korean was a stalemate, but technically the US accomplished what it set out to do (prevent the expansion of communism).
That comment shows an incredible ignorance of history.
