Courses of action:
My possible solution for this global issue is to start a process of banning and unarm this weapons. At the end we will separate all the pieces of this warheads and use them to something else instead like making energy out of them or we could just safe this to develop more and new ways to produce safe and good eco friendly technology from this nuclear warheads that are disassembled. This may be one of the safest and most organized ways to get rid of all this material. Moreover it will eliminate the will of the diverse presidents or leaders that own these weapons to use them.
Apart from this they should also create a law or an organization. The law that we may create will make illegal and will completely ban the nuclear weapons. The organization will be checking if a country is making nuclear weapons and they will take actions in order to erradicate this weapons. The person or president or terrorist that may be creating this nuclear weapon may go to jail by this and although be severly sanctioned.
