well, it can be argued there is a "cold war" going on. For example the crisis with Ukraine was JUST like the cold war with communism. 2 nations battling indirectly for control of another nation /cyberwarfare/sanctions/propaganda/money/supplies/weapons it's been going on in the middle east for a while now, that's why Bush got in so much hot water for the Taliban. The u.s. was pumping money into the Middle east to get popular with rebel force that was overthrowing a dictator, but inadvertently the rebel force became worse than the dictator and alot of their money was given to them from the U.S. it's a dangerous game America has been playing, and Russia has been doing the same thing but they have been more rash about it
but yes. WW3 is coming. If the time for it is soon who knows, but it seems like it's getting there. If people think there won't be another world war they simply don't know history or prefer to live in a false security blanket of delusion
