A historian is not the government? If European countries had to justify every utterance by European historians they'd be busy for a long time... You just keep ignoring how non-proliferation works, if you find evidence that Israel is approaching nuclear weapons capabilities, approaching mature ICBM capabilities, and if you have evidence that they are not quite there yet, then YES nuclear powers should collaborate on neutralizing the threat. There is disagreement if we are or are not too late on North Korea, hence why many oppose attempting to disarm it. But in the case of Iran it's not too late yet. All the nuclear superpowers essentially developed their capabilities in sufficient stealth to attain those powers. This is basic real politik.
