I don’t want anyone to have access to nuclear weapons, since you asked.
But the reality is that some countries, including Israel and the United States, already have them. These two countries are currently engaged in military and terroristic activity in multiple international venues. So if that’s the rules that the big boys are playing with, and then someone else comes along and considers whether they might want to join the party too, your question is I think irresponsible. What you should have been asking is, what is likely to keep the Iranian people safer, nukes or no nukes?
In Palestine and Israel and Iran, it’s fine to look at the governments and say how bad they are, and you may well be right, or maybe not, I don’t know. But we can look at the people whose lives are being destroyed or permanently ended and wish that those numbers went down. If the administrations are full of evil jerks and they stay in power but the death count drops, that’s still a good thing.
