Everything you say here is true, Umair. The problem is that we humans are stuck in the universal law of what I like to call probability balance. This means that stars are born and stars die — creation is always at some point in time offset by destruction, peace by war, ect..
So after a big positive upswing for the West following WWII, we are now doomed to experience the inevitable negative, destructive offset. It is just the way nature works — no exceptions. And of course if it gets to an all out nuke fight that’s the abdsolute end of this balancing cycle for humanity.
