So I gather you are suggesting that the answer to dealing with Iran's potential nuclear weapons capability is to give nuclear weapons to Israel.
I can't help but think that would almost insure the possibility of nuclear war. But if you keep nuclear weapons out of the hands of the Israelis in the near future, it is almost certain the Israelis will find a way to 'disarm' Iran by their own devices. They have a real knack for neutralizing the advantages of their potential enemies.
