US deploys new nuclear submarine warhead to deter Russia

The end of the story tells the tale.
Russia doesn't care about low-yield nukes. There are plenty of big ones aimed their way.
Who would care about such a weapon is the Iranians or DPRK, who like to think that digging a deep enough hole keeps their assets safe. I think this warhead has them in mind.

Thank you for the news share brother Robert

I think we need a wide variety of options, not just the big nukes.
