I believe the majority of Iranians want regime change. I also believe Iranians are a very proud people, and they don’t take kindly to foreign intervention.
Despite what I think, I can’t tell what the average guy on the street thinks for sure, so I’m in no mood to step in and change things. That’s an internal matter.
When it comes to nukes, that’s entirely different. I think the Western nations should give Iran a time table to cease their nuclear program or we should end it for them.
Other than that, no need for boots on the ground. The same regime can stay in place.
