As Sec State Clinton calls President Assad of Syria "not indispensable" the neocons and the Israel lobby want Turkey to invade Syria. Reuel Marc Gerecht writes in the Weekly Standard:
Ideally, we should want to see the Turks establish a buffer zone or safe haven on the Syrian side of the border (Ankara sometimes did this in Iraq to counter nefarious Kurdish activity). Such a Turkish intervention, which would likely be backed by the French, would be convulsive inside Syria and would signal to the military that Ankara had irreversibly chosen sides.
Soner Çağaptay, a resident at the an Israeli lobby think tank Washington Institute, opines in Hürriyet:
[W]hen reacting to the unrest in Syria, the instinct of the Justice and Development Party, or AKP, government in Ankara will be to avoid conflict and opt for a buffer zone inside Syria to manage the likely flow of refugees on Syrian territory. But if that does not work, Turkey could take matters into its own hands, sending troops into Syria. Did I just say Turkey might invade Syria? Yes. And what a can of worms such an intervention would open, humanitarian though it would be.
For those writers the aim of this plot is to move Syria away from Iran and to tie down Turkey in the "western" fold.
Turkey's foreign minister is currently in Tehran and it does not sound like he has any intention to further incite a conflict in Syria:
“Syria is a close friend of both Iran and Turkey, which has close relations with the two countries. It is important for us that there are no more civilian deaths and that the country starts work on reforms as soon as possible,” Davutoğlu said.
Davutoğlu added that Turkey has expressed its position on this to the Iranian side and listened to the Iranian side, adding that both countries agreed on the “inevitability of [the] reform process in Syria and that the process should be completed without instability.”
So it is very doubtful that Turkey will do anything with regards to Syria. But that will of course not stop the usual suspects to lobby for another war.
