It's already shut down for the rest of the week (two weeks total) due to an attack on it by the PKK. Sounds familiar. Turkey is losing $300k a day during the shutdown (total partner losses are easily an order of magnitude more). ;->
This war will certainly roil the investment climate for strategic systems like the Nabucco pipeline. It may be, given the impotence of the West in responding to Russian activities and the extreme value of energy flows outside of Russian control, to help Georgia learn how to deter attack through selective systems disruption.
