Limitool:
Ignoring the error that it wasn't an embassy under attack - I'm sure you've studied this carefully. What military assets were available to respond? It wasn't wise to send more troops into a situation nobody fully understood.
Somehow I seriously doubt the haters would laud Mr. Obama for dispatching additional assets (which weren't available, but that's beside the point) if they'd been killed, as well.
It was called a terror attack right away. The morning after the attack Mr. Obama clearly stated "No acts of terror will ever shake the resolve of this great nation, alter that character, or eclipse the light of the values that we stand for."
The fact that the attack may have had a provocation or other cause doesn't preclude that it was an attack by terrorists.
Where was Libya's government during this attack? You must know the answer to that one.
Making the scene a crater, again without fully understanding what's going on there, doesn't make any sense at all.
Good luck to all,
