I guess World war 3 is all about word war. It is because cold war is finish in world war 2. The world need to improve for the mankind because you know we need peace in the land to continue the mankind. Media is the most powerful weapon nowadays. And family like country family to become solid.
I also think that today there is a lot of time for this issue. It is unpleasant, because it seems that humanity is preparing something for something.
