That's an interesting video. It's a bit different, scenario-wise, than that other one you posted, so I guess I wonder which scenario is more realistic. Can this be survived? Does most of the radiation dissipate after a couple of weeks, or is that a false assumption? How much of this kind of conflict can occur, before nuclear winter occurs, and how many years can that last? And won't more of these things be intercepted, than is shown in this simulation?
I really think that for the past 60 years, the whole military budged should have went to both detection, and the ability disarm these things in action. And big bunkers for the significant part of the public that isn't that rich. All this money spent on tanks and soldiers does not seem efficient
