Exactly. I think also that one things will take care of another. We have no business in regime change.
Those are sovereign countries, with governments formed as the people allow/permit/prefer. Let them decide their own course in that way, just to achieve something approaching stability, then go in and deal with the management if we so choose. If someone is performing genocide, we have the option of stepping in and disrupting those efforts by taking out the bad guys. If they are using WMDs (NBC warfare), take the appropriate action to stop that use and destroy their stockpiles and production. I don't have a problem with that, and I doubt most of the other nations of the world would either.
As for regime change (puppet government insertion), I do not see where that would be a stable arrangement, and with boots on the ground, it gets treacly.
