Not Iran, Hezbollah from Lebanon. Conventional warheads, not nuclear. Missiles from Hezbollah into Tel Aviv would be nothing new. The question would be how many, how powerful the warheads, if it can get through the Iron Dome, how much damage and how many Israelis it kills. I doubt WW3. Who would fire a nuke first? Israel? Sure as shit would not be the US or Russia. Hence the Ukrainian dilemma again and whether the US is truly committed to Israel having to risk a nuclear war with Russia or China. Is Ukraine worth a nuclear war? No. Is Israel worth a nuclear war? No. Also, Pakistan is Muslin, and it has nuclear weapons. It has sold them to Saudi Arabia and could sell them to Iran.
