I believe that the real problem is on nuclear exceptionalism of Israel' nukes.Israel is the only state having nukes without any of its neighbors having it. World would have a moral, legal and unbiased say on Iran's nukes. I believe that Israel's nukes do more harm and than good for Israeli people and Israel politicians are playing a wrong card with it. Israel, renounce at your nuclear weapons, would be the smartest move. Then talk with Iran and force them to do that. Iran is entitled having access to nuclear power for non military reasons, however.
