Let's say that the "majority" of Americans wanted Regime Change, i.e. to install a Communist Dictator with no term limits, like Tim Walz. What do you think the other 49% of the people would do?
It's not enough to have a simple majority for Regime Change. You need an overwhelming majority. Because this majority won't just be fighting the Mullahs and Generals in charge, they would be fighting their neighbors, their husbands, perhaps even their children (or parents) who may be quite comfortable with the way things are.
Israel doesn't have any real clout within Iran. Most Iranians perceive it as the enemy. Israel needs to stop looking through rose colored glasses and see the Iranians for who and what they are. Get the job done, get out and get ready to do it again in about 10 years.
