In the coming US civil war, does either side use chemical or biological weapons?
Please tell us whatever you remember about any new "terrorist" attacks between now and 2020.
Please tell us whatever you recall about any natural disasters (floods, tsunamis, earthquakes, etc.) between now and 2020.
How does the rest of the world fare while the USA is caught up in this domestic distraction? Currently, many nations are virtually completely dependent on handouts of currency, food, and military defense from the USA. Won't that aid be interrupted by the US civil war, and if so, what are the consequences of that? Can Israel even survive without US support? The US currently provides direct foreign aid to Afghanistan, Pakistan, Israel, Iraq, Egypt, Haiti, Ethiopia, Sudan, Colombia, Kenya, Jordan, Mexico, Senegal, West Bank/Gaza, South Africa, Tanzania, Russia, Uganda, Nigeria, Georgia, Mozambique, Congo, Indonesia, Zambia, and Kazakhstan, and many more nations are indirectly dependent on us through their economies. If the USA got caught up in a civil war, in addition to all the above nations being cut off, the economies of China, Japan, and a great many other nations would also take a huge hit.
My point is, you said that the USA and many European nations are places to stay away from during these years, but I'm thinking that all the nations dependent on us would fare even worse.
