In real life he OKed it. In the movie he OKed it then rescinded at the last minute and then got “overridden” by Tony and others at the CIA. Not very good for his reputation.
The “bolder rescue” failed. Reagan got a negotiated release. I think the real agenda was to put a good story on the screen. I’ve seen the movie twice, once just last night, and there’s none of your”agenda” in it, it’s not just in your opinion, it’s from your head. Carter looks like an idiot in the movie for putting the state department in charge of the rescue in the first place then canceling the mission in the second.
A lot a liberals hate Carter too. Remember that “The Swimmer” hated his guts.
Clooney rarely makes stuff without an agenda...especially involving the CIA, politics, Middle East etc.
He's one of the furthest left in Hollywood but go ahead and believe otherwise if you like.
