Passing an exam sounds good to me, but the paranoid part of me thinks that requirement could be manipulated and corrupted. Even so, that would only give you a pool to select from. It doesnt decide who gets which position. As far as having peer selection, that would be very vulnerable to turning into a good ole boy network.
Sure. Anyone with nukes could give them to anyone else, but what happens after? If someone gave Iran nukes, then what’s to stop the US or France or somebody giving nukes to Ukraine or Taiwan. Ultimately it’s too big a risk. Even if two countries are close allies now doesn’t mean they will always be, and the nukes can’t be taken back once given.
