Thanks gandalftb. The only foreign non-power which would risk it is North Korea, but that isn’t too likely.
Should probably keep this speculation to the old threads. But looks like we had a Chinese Sub, launch a missile away from US mainland. They were in the Economic Zone but not inside our Territorial Zone. So the launch was from ‘Chinese Property’. They were shooting away from us. Sinking the sub would have started WWIII. Does it look like we might have tried to shoot it down ? If we did not even try then we are in big trouble. Undetected Chinese subs launching so close that we cannot intercept ?
