I'm not really the buff on all this global chaos, corrupt government, and, of course, nuking city stuff, but as soon as I saw the title (of this thread) I instantly thought about robots.
And there it was.
If we did have a WWIII, it would, indeed, suck. But look on the bright side: if it does happen and we live through it, we will have a crap load of stories to tell our grandkids! Ones better than the old "I had to walk to school barefoot, in the snow, and uphill for three hours a day!" repetitive stories that my dad always jokes about.

And this made me think of something else... I know this may sound pretty stupid, but what about the Mercenaries game? Remember that? If you have no idea what I am talking about, just google it, it should come up. But if you do, it has this weird story of a crazy guy in North Korea taking over both Koreas and threatening to lauch nuclear strikes all over the world. Is that ever going to be possible at all? (I know, cheesy video game storyline, but really.)
