Despite the new missile technology, anyone stupid enough to take a shot at one of our Aircraft Carriers would meet their own end pretty quickly. Firing on a Capital warship is a overt act of war, and is equivalent to firing on US soil. If anyone were lucky enough to actually score a hit on a carrier, they could likely expect incoming ICBMs in retaliation.
Not Obama. He would ask for peace talks.
Plus, look at the recent Korean example. The Norks sank a SK corvette with all hands. The ship was recovered with the intact motor/propellers of the torpedo in the hull, showing Nork manufacture. What did SK do? NOTHING. It's easy to call for instant massive retaliation, not so easy if the counter-counter strike might mean all out nuclear war.
As I recall the warship USS Cole was hit by Yemen with a hole big enough to sink it (had it been a bit lower)with a number of sailors killed too, yet President Clinton didn’t have the guts to respond.
I certainly wouldn’t expect more guts from Obama even over a hit on a carrier.
So is over-running an embassy and holding the embassy staff hostage for over a year - yet nothing happened to Iran because of the "leadership" of Carter. If we lost a carrier under this current administration, they would find a way to do nothing meaningful about it. Even worse, the MSM would portray the loss as the result of U.S. "aggression."
