The quality of falsehoods from the right is just so terrible. Carter was a very good president. The gas shortage was not his doing, but inherited from Nixon/Kissinger middle east policies. They weren't 'terrorists', but radicals, and they were punishing Carter for his humane choice to let the Shah get medical treatment.
So, what you have Carter do differently? Refuse the Shah medical treatment to appease the Ayatollah? Use the US military to save the hostages? Oh wait, he did that, and the military failed him, after which the hostages were dispersed around the country impossible to rescue, only to get killed.
I have an idea - how about Carter make a secret deal with Iran to illegally sell them weapons to get their goodwill? Oh, you say you're not for that? Yes, you are - that's what Reagan did. Reagan didn't 'make the thugs relent', he was their criminal friend selling them missiles.
The hostages returned home safely, as Carter negotiated. Carter did everything right. You want lies, you want wars, you want Reagan committing Iran-Contra.
