Hello, @hisnameisolllie
The question here, I think, is History and reality. No one of the countries that already have nuclear weapons have used it after WW2. They have it, but no one is willing to use it, because they KNOW what would happen then.
But, the countries I´ve mentioned have an agenda to USE these nuclear weapons in war activities, besides the consequences of this act for the rest of the world (we). They have political AND religious "reasons" and have INTENTIONS to USE the weapons.
I think it is much better for the rest of the world to avoid religious fanatics to put his hands on nuclear weapons... and I do not see any injustice in this position.
