Should countries rid of their nuclear weapons? Yes Will it happen at the current rate? No
It doesn't say anything about the probability.
Should they do this? Yes. Is it possible? No.
Should it happen? Of course. Will it happen? NOPE.
people who believe this is possible are not founded in reality
That's the same as asking if every country should get rid of sausage. I'm American and I want my meet dang it! I also want my Nuclear deterrent.
What would happen: Man "YAY THE WORLD IS NUKE FREE!" Oppressive leader with secret nukes "Now that the world is disarmed, I can threaten them to give me everything I want!"
Practically speaking, this is never going to happen. I want America to get rid of its nuclear weapons after China, Iran, Russia, North Korea, and all those other do you radical countries get rid of theirs.
