Close the Roki Tunnel. Cut off the Russians. Put a Fighter Squadron from Turkey over Georgia to defend Georgias airspace, and send Airborne Troops to contain Russsians in Georgia. The Russians are out on a limb here. Lets chop it off.
You’d want a bit more than one squadron. YOu’d want to surge in combat airpower inot Turkey and Iraq and use F-15C’s and F-22A’s as fighter air cover while F-15E’s, F-16’s and A-10’s blunt Russia’s ground offensive and support Georgia troops. We’d need a sizable force of warplanes as Russia would field a sizable air force to defend.
All that said, it’s highly unlikely we’d do this.
