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.
Welcome to the club. Some countries have been doing it for centuries, and some have only recently joined the global game... And what now? A group of people has an unlimited source of money, a stockpile of weapons, institutions, and security services whose sole purpose is to protect that group and their power.
I don't like to sound pessimistic, I doubt we will see some big changes in the near future... at least not big changes for the better. Maybe some future generations will take them down and make the world a better place. We can only hope that the current world rulers don't cause some big and irreparable disaster.
