As long as there is an embassy, it is indeed sovereign territory. Countries may choose to break diplomatic relations, but in that case they are obliged to let the Diplomats and staffers depart the country peacefully.
Anything else, such as the Iranian takeover of our embassy under Carter, is an act of war, and recognized as such by international law and custom for more than a thousand years.
What happened in Egypt and Libya was a severe breach of our soverereignty, and in both cases the governments (installed by Obama and Hillary) were complicit, and should have been held accountable.
Instead, Obama simply ignored the whole thing. The U.S. has sovereign rights? Of course not. Only other nations have sovereign rights—as long as they are politically correct sorts of nations. Israel doesn’t count, and neither did Libya under its former ruler.
Using your statement, my point is more that our embassies are only as sovereign as our country and government are willing to make them so.
If we have a pantywaist, muslim sympathizer in the White House, then we have no such thing as sovereignty.
Your post is very informative and accurate, in regards to the legal situation, but the reality in Libya is very abberant.
Even before the awful murder of Ambassador Stevens, the Libyan govt had disregarded the principle of diplomatic immunity by imprisoning an Australian lawyer who was let into the country as a representative of international court. It was very difficult to get Melinda Taylor released. This was a curtain raiser for the events in Benghazi.
