I like that idea. It would need to be further fleshed out, but a good start, so far.
In the meantime, I don't see a reason why we would have any right to send our military to save other nations from their own failings, unless it is a direct and MAJOR ( think, platoons invading our home soil, shooting at our own people in areas of large population; something at least of that scale) threat to our home field.
I'm all for peaceful humanitarian efforts, even sending funding to legitimate repair efforts (provided that the money is used for that, as opposed to falling in the hands of the next native warmonger to screw things up again); that stuff I'd be cool with our gov doing.
But I'm not for sending in weaponry, funding for militias, troops, or anything of that sort. Call me horrendously cynical, but I bet that odds are, had we intervened in Rwanda, it could have escalated into something much, much worse.
