An enormous nuclear submarine poses a real threat in the ocean. You could have no idea that it is floating beneath you, and yet it carries a thermonuclear weapon that could destroy an entire continent!
Quiet and inconspicuous, it can lie on the seafloor for a whole year, waiting for the order to strike!
You would think that such a deadly weapon would be banned, but recent events suggest otherwise:
Not long ago, a Russian doomsday submarine was spotted in the Arctic. It surfaced in the middle of the ice, stayed in that position for several hours, and then dived back down. What’s interesting is that Putin himself hasn’t been seen on TV for quite a while now, and what better place for him to hide than in an eternally frozen wasteland, armed with nuclear missiles?
