If an AC-130 was on station. And if, as has been suggested, it was not utilized out of some concern about "violating Libyan air space," then that would truly put this event in the category of Watergate as far as presidential scandals are concerned. Any consulate or embassy is soverign territory (which the host country by treaty is obliged to protect). Any attack on a diplomatic facility is legally the same as an attack on US soil. And we have the right (not to mention the obligation) to respond in any way we believe is appropriate. The attack on Benghazi went on for 7 hours! We could have intervened at any time and probably saved lives. POTUS sends these people into harm's way and he is responsible for doing what he can to protect them.
When Colonel Gaddafi engineered an explosion at a disco in Germany that took the lives of American GI's I don't recall Reagan having any concerns about "violating Libyan air space" when he sent the FB-111s on a mission to kill the Colonel, or at least get his attention.
The Obama administration is furiously covering up what happened in Benghazi. Trying to run out the clock until after the election. I have reworded what was said about Bush for the case at hand: "Obama DENIED. . .people DIED. . .then he LIED."
