Ctlawyer,
It means that if a US citizen, corporation and or its holdings are subject to action by a foreign country, the embassy staff does its best to see they are treated fairly..meaning no different than citizens of the host country. Since Embassy/Consular grounds are treated as if US soil, the protection you cite is off those grounds.
Do you have a supporting proof for this besides yourself?
Additionally, the words “property and interests” disputes that claim, also if it is us soil then there was an attack on america’s land (a cause for war) even if it was “because of a YouTube video”
Since we’re using sports term I guess I’m calling a penalty on you
