It must be clear to both Syria and Iran that:

* Iraq will not fall apart

* President Obama wants to withdraw all our forces as soon as possible from a reasonably peaceful Iraq.

Syria and Iran could facilitate Obama’s desires for their own advantages. The sooner and more completely that the USA withdraws from Iraq, the better for Syria and Iran.

Then all three of those countries might want to buy lots of US military aircraft.

The Syria-Iraq-Iran region is where a grand deal with the USA is possible and mutually advantageous.

The Palestine-Israel-Lebanon region is where a grand deal is still as impossible as it ever was.
