Will maybe those who do worry about Israel's nukes are "nobody" to you, but they are somebody still. It seems to be me your western centric bias is not one that can be challenged that easily! Incidentally, those who do worry about Israel's nukes know that Israel is the most likely candidate to use nuclear weapons. It has already brandished the nuclear card in the past, during the 1973 war for instance, and has been implicitly brandishing it around more recently as well. (The next top candidate to use nukes is the US, which is the only country to have used them in the past, and which has refused to rule out using nuclear weapons again, including against Iran specifically). Iran's nuclear program, on the other hand, is only a threat to those who want to threaten Iran with nukes. Otherwise, Iran's nuclear policy (even if it isn't solely focused on nuclear energy) is meant to give Iran surge capacity, i.e. the ability to build nuclear weapons if required and threatened. There is absolutely no other utility for Iran using nukes, when the other side (both Israel and the US) have plenty of them and have shown no compulsion to threaten its use in various scenarios publicly discussed, without Iran having officially built any nukes yet. At the end, I don't care what you think. You can imagine your worries are shared by the "world". And imagine that "nobody" cares about Israel's nukes. That just speaks to how fundamentally imperialistic are western notions of who is somebody and not, and whose worries matter and not.
