The pullout of US troops in the Middle East is likely to continue after November's presidential election. We're already seeing significant changes in how the Middle East works, including what sorts of antics local players can get into when the US is distracted. And for once, Iran isn't at top of mind. Iran is a known quantity at this point, making whatever moves it can from a very constrained set of options that it has been relying on since 1979. Rather, it's the Saudis, the Turks, and everyone else who has been wholly dependent on American protection since the end of the Cold War (if not World War II!).
NB: at 1:46 I definitely meant to say *Turkey.*
