There’s literally no on on planet Earth who thinks that the Ayatollah and that regime were a good thing. Okay, nobody outside of Barack Obama, Ben Rhodes and that crew of foreign policy people.

None of those people thought that the Ayatollah and that regime were a good thing, either. They simply realized that the downsides to simply attacking Iran completely outweighed the potential benefits, because the amount of military engagement necessary to actually dislodge the regime (rather than what we're doing now) were enormous and incredibly risky.

Only the foolish believe that the reason prior Administrations didn't just go out and attack Iran is because they thought the Ayatollah and the regime were a good thing. Also, only the foolish believe that the reason prior Administrations didn't do that was because they were weak. Like Trump seems to believe. Rather, they were simply wise enough not to act recklessly.

Next, this war has a higher purpose. Care to hazard a guess as to what that is? And it’s not on your list.

There have been easily a dozen different "higher purposes" offered by the Administration for the war, and still more that have been offered by pundits and apologists. Of all those different possible higher purposes, I have no way of knowing which one you're referring to, since you give no hints. Perhaps you could tell us?
