World War 3 is not likely to happen. All of the major superpowers(USA, China, and Russia) know that war wouldn't be good for either side. More than likely, everything will be worked out without war. What good would a war with the United States do Russia? It wouldn't. They know it, you know it, we all know it. It would just kill millions of people and get us absolutely nowhere..
Oh wow... you're a genius. It must be a completely new idea that war is bad for both sides... That's why we had so much war in the past, people didn't realize that!
Not for everyone on both sides, only the weak poor non powerfull people. They get rekt while the govement can just chill.
