Benghazi with a twist

[JRP1994]

Let's say that Benghazi happens as it did IRL, but instead of the real-life response, Obama makes a more Machiavellian play:

1) Immediately declare the act a terrorist act.
2) Strongly emphasize the Al Qaeda ties.
3) Start bombing stuff in a highly publicized manner

How would this play have affected the 2012 election? It would have taken away Romney's entire narrative of Obama's response being weak.
