It would be nice, except a Pakistani ship with a nuke in the hold could approach Jaffe harbor and as the Israeli naval forces approach and ask to board, detonate itself, making the mother of all suicide bombings.
Forgive me, but as attractive as nuking Iran sounds, it’s not doable.
Israel certainly is capable of taking out Iran: Jericho 3 ICBM with its MIRVed warheads. Popeye Turbo cruise missile with its nuclear warhead. Do not underestimate the Israelis and their ability to strike an enemy where least expected. Iran with nukes is like lighting a torch in a powder magazine.
