> How is Georgia any different from Finland in that regard?
Basically there's isn't a difference, Finland shouldn't be in NATO either. Americans have no business defending Finland of all places. Georgia is even less of a concern, it might as well be on the moon for all the national interest we have in Georgia.

Right, the cornered dog theory. Maybe he'll bark himself to sleep before he bites you.

The alternative is that countries negotiate with regional powers and try to maintain friendly relations. The US is not world policeman and we can't afford to play one on TV, because it invites situations like the Ukrainian one.
