Maybe that's the theory, but it's pretty doubtful that North Korea has enough competent frogmen to carry out such an operation. Combat swimmers are pretty much the most expensive and difficult to train special forces there are. Look how long, expensive and difficult the training pipeline for one singular US Navy SEAL, and those guys are generalists that have only conduced one known successful combat swimmer mission, and it came pretty close to going horribly wrong (almost got ran over by a cargo ship). North Korea though has used minisubs to attack South Korean shipping harbors/lanes and kidnap South Koreans/Japanese civilians. It's a far cry from doing it against the US Navy though.
