The US military is spread thin. Putin unlike Bush is no fool. He knows when to strike and where.
DO NOT forget last winter they cut flows of nat gas. This is serious gamesmanship. I think someone like Boone Pickens is who we need in the drivers seat not these Bush McCain clones.

Putin has been licking his wounds for decades. Russia is ready to reclaim superpower status, with energy control as a key part of the agenda.

Russia wants to put the US on notice that its goal of increasing regional influence and boxing in Russia won't work. I imagine Russia wants the US to drop its missile-shield plan, in exchange for "playing nice" for another few years.

However, if the US doesn't back down gracefully and Russia continues to press Georgia, the US will almost certainly press back somewhere, probably a limited attack on Iran's nuke facilities and air-defense network. Unlike Vietnam, though, where both US and Russian actions had long logistics tails, the Russians are playing much closer to home this time around, and they are in growth mode while the US is struggling. They can needle the US without much effort, while the US will be hard-pressed to increase the force level in the gulf region.

Certainly there is an opportunity for this conflict to increase regional instability, and any of the hot locales could potentially involve a few mega-barrels of oil in production.

Boone Pickens is no Jack Kennedy....
