Global Thermonuclear War is just that, Global. Even now, after stock pile reductions, we have enough Nukes to char the entire surface of the planet. With Armed Services Bases all over the world, most every place would have to be targeted to some extent. So, other countries would be dealing with their own issues and welfare.
As for any Star Wars thing, even in this game, that weapon can only be shot once a day. I can't see any military only sending over one nuke a day. The Star Wars system that was envisioned back in the 80's was not feasible even in it's hypothetical phase. Even at it's best, that system was only designed to reduce the number of Nukes to a manageable level, whatever that is. The goal of Nuclear War was to Survive, not to win, so a couple million people left alive was good enough for the Military Planners of the time. Today we know the Star Wars Defense System, or SDI was a smoke screen, an illusion.
All of this, it's really just a matter of
when? Isn't it? Ready to unfold. I like politics, always interested me to a certain extent. Would there really be vaults ready for the citizens? The government has bunkers stocked with food and medicine for years. An EMP could devastate the entire continental United States. Iran for example, just for [censored] and giggles. Hundreds of millions dead? That's the part that's scaring me. No body is prepared for it, there would be panic, starvation, no co-operation, anarchy, disease. There would be no medicine, diabetics, all people undergoing surgery, people on life-support, all dead. Society would crumble as would many other nations as a result. Maybe China? They could EMP us, knowing the possibly outcome, EMP all of Europe as well, nonchalantly and secret of course. Could do it from a ship, no symbol or identification.
One ship in the Mexican Gulf and one in the Mediterranean. Once they've EMP'ed Europe and the U.S. They can wait a little while, then send some aid, help rebuild, etc. They'd bring troops of course, plenty of them. They'd claim they were helping to aid and they would do a lot. Would the troops and doctors and all of those people leave? Of course not, they would stay. They would stay and take over North America. What's to stop them?
