I think that is an unfair question. A situation like 9/11 had never really happened with the possible exception of Pearl Harbor. After the attack most Americans were looking for some answers as to what really happened and why. Had this happened during the Obama, Gore, or any other administration I feel there would have been the same sort of confusion. It is interesting how the left side is clamoring for more Arab springs but they bitched when Sadam Hussein, the killer of thousands of his own people, was brought down.
We are far more experienced now and decisions are easier to make. Obama hasen't really removed the U.S. out if the mideast. He has just shifted the countries and the type of warefare using newer technologies. He is fighting a very descreet war and keeping it out of the press as much as possible.
All of which is unnecessary with a sound U.S. energy policy.
