In a move that seems straight out of a James Bond movie (ya know, where the villain sentences the hero to an oddly slow death then conveniently leaves the room), Putin has apparently threated to fire off a nuclear missile into the Atlantic Ocean that would create a 500 meter radioactive wave (no, I have no idea how big that is either. Dumb metric system) that would then crash into the UK causing devastation.
... f*cking WHAT? Yeah, gonna call that bluff. If you have a nuke, why would you make a tsunami? Seems a bit too complicated.
