We will have to wait and see how it plays out among the various political groupings in the Middle East, Europe and the USA as well as the two protagonists. My own thinking at this stage is that Iran will seek negotiation. "He who fights and runs away lives to fight another day" The leaders will want to hold on to power. Israel wants to draw in the USA to finish off the regime.
The biggest problem with this is that Trump said "unconditional surrender". This must mean that Iran is taking an incredible pounding by Israel and its leaders can be taken out due to intelligence and precision munitions. Trump now cannot be seen to lose face. He cannot back-track without looking extremely stupid. That's not going to happen.
I think they will take out Irans launchers and relevant sites. Once this happens, it's game over and Iran is a sitting duck for destruction from the air, because Israel can recover.
