A little more complicated than that: invasion of Kuwait, 1st Gulf War, chemical weapons, WMD confusion, violation of UN sanctions, post 9/11 fears/unknowns, concern about impact to global energy economy, etc.

One of the benefits of the US energy leverage created by fracking is that the energy market considerations that were part of our Middle East policy aren't as important any longer, we have many more degrees of freedom in this regard. I believe there are other benefits that come from less money available for state-sponsored terrorism/extreme groups due to lower oil prices.
