I don't think they got together and said it (but who knows). Either way, it doesn't matter, they did do it.
Whether some warring nations had some of its warriors killed is not the question. You claimed it was the foundation for why people came here. That couldn't be further from the truth.
Well, I'd say just about anything is better than killing all of them and taking their land ....
All of them? There are none left? Or, do you mean defeating those nations in war and conquering their land, like most every nation has done?
It was the founding act of the nation .... face it, the first thing we did when we got here was accept their generosity and knowledge, and then killed them and stole their land (as obviously evidenced by the lack of native americans walking around (and don't even bother saying reservations, because everyone knows that's b.s.)).
The founding act of the nation was leaving an oppressive religious atmosphere to establish a different oppressive religious atmosphere here. Then, when we conflicted with those that already occupied the land, we settled the differences in the manner that was the norm at the time.
As for no American Indians being around now, that's just dumb. They still exist, or we wouldn't have them to talk about. Is it crappy they got shoved on reservations? Of course, but that doesn't mean they don't exist. They are soveriegn nations still, with the land we left them (just like Mexico). Except, of course, they have all of the advantages of being American citizens, too.
Also, we don't currently occupy Germany or Russia or Spain or England, so I'm not sure I see what your point is. Also, wars already started on others soil where we go to assist are radically different from simply waltzing in a country and killing EVERYONE.
The American Revolution started on English soil, and ended on American soil. The wars against the several different American Indian nations started on Indian soil, and ended on American soil. It just works that way. We don't still occupy Spain, but we occupy many areas that were Spain's, but they're now ours. And French soil that's now ours. And, English. And, American Indian.
As for Mexico, we didn't so much steal from them as we stole from them after they had committed their particular genocide. The land wasn't theirs to begin with (but that still isn't really much justification).
In short, genocide is hardly something you should be trying to justify.
WWJD baby.
I'm not justifying genocide. I'm attempting to correct your perception to reality.
