Issandr el Amrania joins the debate:

[W]here Obama fails more generally is that, at a moment when the policies of GWB meant that American foreign policy needed a radical overhaul and conceptual rethink — most notably a withdrawal from the Middle East — Obama shied away from that.

You might argue he tried somewhat on Israel/Palestine, but I do not believe that attempt was genuine. More generally, in the Middle East at least, policy has been more of the same and continued support, post-Arab uprisings, for the traditional dictators/allies of the region: pro-Saudi and pro-Khalifa in Bahrain, pro-SCAF in Egypt, a massive surge in spending to protect the Jordanian monarchy (or more accurately, King Abdallah’s current power structure), pro-status quo in Morocco, etc. I will concede a good reaction on Tunisia, although we don’t know the details there yet.
