What sort of sick bastards dream up this kind of weapon? Whether or not the Russians ever build it is almost beside the point. Simply announcing to the world that you find this to be a reasonable approach to deterrence should be enough to mark you out as a dangerous creep.
The world’s anti-nuclear hippies, with their purple hair and piercings, are a heck of lot more sane than Putin, with his grotesque plastic surgery, coterie of doughy generals, and ghastly underwater bomb.

Excellent!
All should read up, even, but real up might have been a good way to put it, too. ;-)
