In 1980, I supported a much bigger commando raid against Iran, and perhaps more. Well, I was wrong, and President Carter was right.
You didn't even need that.
Frankly the Ayatollah was not suicidal, he was a religious asshole, but those who thought he was suicidal a la in modern terms Zarqawi or Bin Laden completely misread him.
Carter announcing release the hostages or in 48 hours we start bombing one of your oil fields after another and the hostages all would be released unharmed before the second hour was up.
A Commando Raid even if partially successful would get hostages killed the other way would not. The Ayatollahs really are very smart at gauging the line of US leaders and they did figure Reagan as a man who would bomb them and pegged Carter correctly as a man who wouldn't.
