I have to disagree. Regime change is only going to happen if boots are on the ground like with Iraq and that is not going to happen. Trump has not shown any signs of doing that and he has no need to. Eliminating the nuclear threat is the mission.

Now the regime is already fragile. They had those mass protests the last two years but now there are calls from inside the country to calm down and take a step back. The military obviously isnt as strong as Iran wanted people to believe and Russia isnt bailing them out.
