Imagine you are working for the us government in 1946. what measure would you propose to curb the development of atomic weapons? how about modern day iran or korea?

1946: Make sure that Henry Wallace was on FDRs Ticket as vice president.

Iran and Korea: Iran might be a threat to Israel, but North Korea really isn't a threat at all. I think the United States would turn North Korea into a parking lot if they dared use atomic weapons. Everyone who has them is terrified of using them, and there are many countries that do. The best example I can give you is India and Pakistan. They regularly go to war, but neither would dare use their atomic weapons on the other.

which time period is this? or is this story fictional, i'm going to need more info to answer this question
