I also personally don't like Israel having nukes. The more countries in the Middle East with nukes the less stable it is.
At least between the USA and the USSR the divide was idealogical, a fanatical religious divide seems far more dangerous to me. I don't know if M.A.D. is enough to stop fanatics from lobbing nuclear weapons around.
People only resort to violence if A: they are reasonably sure they can get what they want with it or B: they feel they have nothing to lose. Iran is really in neither position, or at least the Iranian leadership itself is not.
They will hold
