Agree with 74 on this. Russia, China or the U. S do not want a nuclear war. That is not how I believe what will happen. The war will be a grid down, EMP attack but not a nuclear attack which would mean the riches of that country can’t be used or taken be the attacker. Everyone wants something. China want oil and water which the U. S. has, Russia has oil too so do the attacker wants to radiate all of the riches, NO! They want to take the riches. So EMP is a good one for them.
Also a bio virus maybe in the works too, kill 90% or more and keep the riches for the future.They become the one world order.
