Nuclear energy is the future, is what scientists say but nuclear weapons are the risk. When the nuclear bomb was dropped on the cities of Hiroshima and Nagasaki in Japan by the United States marked the beginning of a new era, the era of the Nuclear weapon.
Lets have a look at how many would be needed to wipe out Human beings, seriously!
Wiping out civilization completely is much more profitable when the process is slow, for instance by poisoning water and food like is being done right now. It will inevitably force people to take medication and if that is stuffed with venom as well it will ultimately be as effective as the nulear destruction option, while Big Agro and Big Pharma will earn trillions of dollars along the way in executing their programs. An other advantage of decelerated destruction approach is that it is possible to more precisely decide who is allowed to live after the genocide while not the entire planet will be in a nuclear winter for centuries.
