Then why all the fuss???<quoted text>
It is impossible to defend any embassy in a foreign country from a coordinated military attack carried out with the consent (or at least lack f opposition) of the foreign government.
BTW if you google Benghazi you'll find a map that can be switched over to Google earth, all these places of interest are actually identified and you can see what they look like.
Well not the embassy, because it was clear the fk back in Tripoli but you can see the US consulate, the British consulate next door and the nearby annex which we have now learned was actually a CIA base.
