I think it is way too soon to make judgments in general.
What we have learned is that Libya did warn us.
We have also learned that the Obama Administration lied to us for a whole week about this attack on our consulate in Benghazi. Why would the one term Marxist and his Administration lie to us? The murder of four ambassador did not even slow down the fundraising and the partying. "The peasants are starving." "Let them eat cake."
It is such a good thing that the one term Marxist will soon be relegated to the "WTF happened" portion of the history books.
