Wrong our ICBM's and SLBM have inertial,steller,and gps navigation. We can still nuke accuratly any country on earth without gps. Or dont you remeber the world befor gps when we still had ICBM"s and SLBM's. Trust me they cant cripple our nukes if the knock out our gps.
Thanks for the dose of reality. I had a hard time believing we'd be that dumb. The russians could surely take out a satellite for some time now.
