For Iran, it seems the regime will stay in power, you can't remove them from the air. The geography and population size of Iran will prove more challenging than Iraq or Afghanistan. There is very little support for Trump's War. They never sought to persuade the people, it appears they have no plan b (which they wish to be illegal /s)

Hubris is an apt way to describe Trump's approach to Iran. One evidence to this is that they thought Venezuela was the model for Iran. A SA dictator is nothing like a religious movement that has taken root for ~50 years.

What does winning look like for the US & Israel? Trump has already claimed they won, but have more winning to do. What they have said changes daily and between who's talking. I imagine this will continue after hostilities end, they will backfill their goals to claim they "won", like so many other things they do this with.

The real winners from this? Probably Russia and China more than others.
