I have come to understand that the countries we mostly refers to as world powers or the big five like USA, Russia, China, Germany etc all deals with nuclear weapons that post treats, fears and minority orientations to other countries. Countries like Arab, Iran, Irag, Pakistan and lots more have powers but do not actually have nuclear weapons to withstand or fight the big fives countries rather it has always be a thing of negotiations for resources, boundaries and scales rather than fights and win battles to know who control the world.
Africa has millions of people but can't boast of any weapons except retires guns and stainless used and abandoned by America's and Europeans, and that's why Africa can not stand for their rights like Burkinafaso today,
You can correct me on this statements.
Of course, we have big countries > underdeveloped and 3rd world countries. That's why there are imbalances in the world. Those progressive countries have a lot of nuclear scientist and physicist that can developed more potent weapons, a weapon of mass destruction.
Hopefully though, the sitting world leader wouldn't think of using it's nuclear weapons as it could lead to a world war 3. As for the poor nations, it's going to be very hard to acquire even one of this nuclear weapons, priorities are going to be very different.
