And so that has shown the difficulty of reassuring allies. South Korea is so nervous that it has been talking earlier this year about the possibility of getting its own nuclear weapons, not relying on the U.S.'s. And sometimes it's actually easier to deter the adversaries than to reassure the allies. Whereas if they travel into the shallow waters near the Korean Peninsula, they'll be more vulnerable.

However, critics say that, you know, sending the submarines is really more for show because they could fire these missiles from a far greater distance and they'd be safer. move to send a submarine?

And on top of that, tensions are increasing between China and U.S.

The U.S., meanwhile, is expected to send a nuclear-armed submarine to the Korean Peninsula - first time in decades that's happened.
