There are anti war protests in Israel against Netanyahu since Hamas attack on the October 7th. As soon as the fighting ends an new election will be called and Netanyahu is probably going to loose that one. That would mean a more moderate government for Israel and the chance for a deal with the PLO. However a war with Iran delays this and we know what is going on in Palestine right now.
A weaker Iran might help, but the way of getting rid of Iran as a problem is a revolution within Iran. I doubt a war against Israel would help with that.
No elections are scheduled to be held in October 2026, but the coaltion is very likely going to break as soon as the war ends.
