If only we had a rapidly-deployable, amphibious force in readiness. Oh wait. We do.
Rest easy anon. Marine Security Guards have the interior of the mission protected and the 100 Tuefelhunden deployed with 2 death by rotary wing packages mean it would take something serious to overrun the embassy.
Guaranteed a gorilla package is on standby if things escalate and the embassy needs reinforcements. This isn't war. POTUS exercised restraint when Iran shot down a drone a few months back. No reason to think otherwise here.
