Iran already has the missile means to deliver a nuclear weapon to Israel. Last year it unveiled its new missile which unsupringly has a range which reaches Israel. Iran is now working on its nukes and time is running out. It is safe to say that Israel is already planning its own measures to deal with this terrorist threat. The world will probably do nothing, and Israel, yet again, will have to act. But it may not bomb Iranian reactors, if it finds that its own missile defense system is deemed able to intercept any such thing coming from Iran, or if the US or another entity sucessfully persuades Israel not to act, but that is unlikely.
Unlikely indeed. I wouldn't bet Tel Aviv on it and i doubt Israel will.
