"Are they insane?"

That pithy question is echoed, perhaps more politely, by a senior US diplomat in this Reuters story:

One senior U.S. official, who spoke to Reuters on condition of anonymity, acknowledged that the U.S. defense of Iranian compliance was “weird” and did not come naturally.

And why is this official in such a “weird” position? Because of this one weird belief:

“Iran has done a lot of bad things in Syria and across the Middle East, and still does. It’s holding Americans hostages. But the fact is, it’s complying with the JPOA.”

What exactly, given Iran’s behavior “in Syria and across the Middle East,” or holding hostages, or pursuing nukes, or anything else, gives our esteemed diplomat the belief that Iran is complying with anything, especially the JPOA?

“Insane” is right.
