Maybe we should start a separate topic for this discussion?
Thread creep - it happens on here a lot. Not an issue.
In the US it just takes one white cop to shoot an un-armed black kid, and people will use it as an excuse to riot and dapple in some five fingered (cash free) shopping.
Or armed - it really doesn't matter a whole lot. Going that way leads to political discussions, which aren't allowed on here for good reason.
Whilst I can't speak for the USA, the UK needs just 11 missile strikes to effectively bring it to it's knees and put England back to the Victorian era.
Technically, you MIGHT be able to do it 3 - 4 EMP devices. We've had THAT discussion in a different thread, beat that horse to death, resurrected him, then beat it to death again. The 'One Second After' series by William Fortschen is a good read.
I'm going to have to creep a little bit of politics in here, but this also goes in line with a series of books by John Ringo, the 'Troy Rising' series. One of the biggest differences between England and the United States is size. I live in Oklahoma City, Oklahoma. I could drive from here, to Corpus Christi, Texas, and it'd be about the same as driving from Inverness, Scotland, to Plymouth, England. The size of Oklahoma ALONE is 13,000 square miles larger than England, and Oklahoma City is larger than London, with not even a tenth of the population. (Seriously, 620 vs 607 square miles, 700,000 versus 8.9 million.)
I'm not saying that a dozen nukes along the east and west coasts wouldn't cause a lot of turmoil and chaos in this country. It certainly would. It wouldn't destroy the country, though. Heck, even back in 1983, when the movie 'The Day After' came out, and they hit the U.S. with 300 nukes, it didn't destroy us. Fucked us up a lot. We're just too damned spread out, though, is the problem.
You'll note that this whole thread spread comes from your comment here:
If you use a nuke, you wouldn't need to, as there wouldn't BE an enemy...
Oh, and there's nothing much more fun that full MOPP 4 in Alabama in the spring and summer. (When I was in, the US Army Chemical School was at Ft. McClellan, now it's at Ft Lost in the Woods (Leonard Wood).)
