So, I’m just on this.
I want journalists and pundits to call this what it is.
The take down of the US Embassy.
That the former SEALs were lasing the mortar position indicates they believed someone in the AO had the ability to put steel on target. That fire/air support was not forthcoming, and only their actions permitted the people who did escape to do so.
As has been pointed out here, only, repeat, ONLY the POTUS had the ability to grant cross border authority. The buck stops there.
