It is very very important for the US not to get involved in any way, shape, or form. Iranians should be completely in control of their fate and decide what regime they need. Any involvement from outside forces will severely undermine the next regime because it will forever be seen as an imposition from colonizers. The US already interfered to remove an evil dictator from a country in the region and created a mess of incalculable proportions. We clearly don’t understand these people and shouldn’t be messing with them.
If we haven’t learned even this, we have learned nothing.
