If Iran can get a sustained supply of missiles in large numbers then I see no way Israel is going to come out ahead: Iranians are proud, tough people, used to much more deprivations in life than the Israelis, many of whom would book the next flight to Berlin or New York.
The game changer, IMO, is Trump's threat saying things like 'negotiate or nothing will be left in Iran'. What an immoral warmonger who false paddled a 'peacemaker' Presidency and fooled too many people in the 2024 elections, including many stupid Muslims.
