world war 3 could possibly be North Korea the US.
China could be a possible supporter of North Korea.
The US has already been in war ever since the world war two. I
doubt any world war will happening soon.
Besides, what would any organisation gain from all the dead
humans, they'd rather use us to make more money and live their
lavish lifestyles.
Only more wars between the US and some random country will
occur.
If there should be a world war 3 it would be a war between
humans and the global change in weather..if this point is valid
then we are at constant war.
