As much as we've needed one since '91, it won't happen. Iran and Turkey are against it, and with Turkey being a NATO member...
We certainly owe it to them, we've led them on, abandoned them, etc., and they still like and support us. Outside of Israel, they would be the only really stable state in the region that is not wrapped up in or controlled by religious fanatacism. Hard to count Turkey in that mix as they tend to waffle.
