The majority of Arabs don’t want Hamas leading them!;the majority of Lebanese don’t want Hizbollah and the majority of Persians don’t want the Ayotollahs. Given those demographic parameters, the most intelligent American policy would be to support the people against their self-destructive, oppressive leadership. Bur America, to be effective, would have to do that in an overt way-openly and transparently. The Covert CIA type intervention only leads to more mistrust and conspiracy theories. And I don’t know if the American polity is up to the level of sincerity and integrity that kind of intervention would involve.PS If you need more details then you can engage in a discussion about the mechanics  that kind of  operation would involve!

PS Ironically,the precedent for this would be the way the French ,regardless of their motivation,helped the Americans win their war of Independence. Time for payback lol?
