Well first at all Iran does not pose any threat to Israel. All the comments by Iran come in response to Israels and US hype about the nuclear program. I think that Israel should not scare its own people and force them into unnecessary actions. There is deep hypocritical tendency by Israel and the West when it comes to nuclear weapons. Israel wants to be the only country in the region that posses such power so that they can protect own and the wests interest in the region. Once Iran acquires nuclear weapons they will be having much more options and also enforcing their own interests in the region. We all know that one of these interests is oil at least for the west and Israel. Now the one thing that I am concerned about is the Iran's neighboring countries. Iran will become the regional bully and the suni states will be constantly under threat. I do not believe that Iran would go into a nuclear showdown with Israel and even though Israel will lose power in the region there will be no threat to its existence.
