Wut... If America wanted to cleanse the earth with nuclear fire they could have done it in the 50s/60s...
Because a few will hurt. Thousands will kill everyone. AKA do not try to kill the guy who'll kill everyone... And Britain only has around a hundred or so I think at most. Wouldn't surprise me if we have twenty.
So basically you guys took the whole planet hostage and started screaming, "DON'T FUCK WITH ME! I'LL KILL US ALL! I'M TOTALLY SERIOUS!" while pointing nukes at everyone?
