IIRC, the Black Sea would allow the Navy to launch on Iran, or at least be within range. Not sure why, since there is no place on this planet that it out of range of the US Air Force.
The Navy can hit most anywhere in Iran from the Indian Ocean also, I think. Then there is that big air base in Afghanistan. No, it isn’t basing or logistics that is the problem with military action in Georgia, it is the lack of testicles at the Pentagon and White House.
Considering that a B2 could load up on bombs in the USA and deliver them in Georgia about 16 hours later, the ENTIRE USA is a logistics zone for an air campaign over Georgia.
So that makes any logistics arguments bogus and a smoke screen for something else.

I think what happened here was a White House meeting where it was decided that State would carry the ball. The last time that happened was in ’03 in Iraq with the appointment of Bremmer. We know what happened there. State fumbled on the 2 yard line and we got a nasty little insurgency for our efforts.

They still there? 16 days and counting.
