We can do what the Bush Administration seems to be doing, if perhaps somewhat belatedly – support Georgia’s government with humanitarian aid and shuttle diplomacy, and (depending on the decisions Moscow makes this week) with sanctions of various sorts as well. But committing ourselves to "coming ashore" for Georgia – whether through a proxy war or the security guarantees that come with with NATO membership – just doesn’t strike me as realism of any sort, given the strategic necessities facing America elsewhere in the world.
