I impugn the data you provide, Steve (the original source, I mean). I believe they should be more rigorous.
This is one of the links available to the American wars. Interesting story. It does not include the wars against the native americans.
http://en.wikipedia.org/wiki/Military_history_of_the_United_StatesNot all of them are real wars. Many are armed interventions, some are just skirmishes. Many of such armed interventions have an official UN authorization so that's called more rigorously peacekeeping intervention or humanitarian intervention.
Sometimes armed intervention becomes a duty for a nation, like in the case of the UN intervention.
I cannot say much of the wars against the natives because I don't know them but, in the latest 115 years, not many real wars have been fought.
We might discuss them one at a time, it's very interesting history anyhow.
