As noted in many mainstream publications, such as a recent piece in The Australian Financial Review, January 18, 2023, Russia has moved ahead with its doomsday weapon of a nuclear torpedo, called “Poseidon,” which they say is “unstoppable.” The torpedo can be remote controlled, moving into position for attack, and can sit on the sea bed, and wait. When detonated, it would produce a tidal wave of radioactive water, to destroy a coastal city, which is most main Western cities. The nuclear bomb to be carried is 100 times more powerful than the bomb dropped on Hiroshima. Russia has already threatened to sink the UK under radioactive water.
This is but one of a new set of weapons of mass destruction that Russia has developed while the West has worried about woke issues. I have yet to see any proposal about how these weapons could be countered. It does not seem a wise move to fight World War III with these deadly weapons floating, or rather swimming, around.
