The US never wanted a "good member of the family of nations" out of Iran or anywhere else we fucked up. We wanted to keep resource-rich nations in the dirt so they could not collectively bargain against our corporate interest, and they did not care how many people got butchered along the way.

You only have to look at the absolute sons of bitches we've armed and bankrolled over the years to know our crusade against socialism was never about freedom or dignity.

War wastes a lot of lives and the US seems to do war mostly, so this microcosm of war is no surprise.
