By "others", you presumably mean credible threats from enemy states (since we allow Israel to secretly harbor nuclear weaponry with no problem). But no, I don't think that. I think it's nuanced, and I think that it's wrong to frame it with language like "let", instead of saying it like it is: starting a war to intervene. War in the Middle East is historically a bad idea, and there better be a good reason to justify the senseless death. I think the seriousness of that decision should not be minimized by statements like "well we couldn't just let them do anything". There is a serious chance of this escalating into something far worse.
