What Is Turkey Doing In Syria?

Turkey appears [NYT] to be providing support and shelter for the Free Syrian Army, an anti-Assad military organization. Daniel Serwer freaks out:

None of this is good.

Violence–however justified on moral grounds–is going to make it harder for the protesters to win over minorities in Syria and opens the real possibility of ethnic and sectarian warfare that will spill over Syria’s borders into Iraq, Iran, Turkey and Lebanon.  That could become a truly serious mess that all concerned would regret.  It is time to ask the Turks to keep the Free Syrian Army inside Turkey and to stop playing with fire.  If they want to do something, some stiff restrictions on Turkish business with Syria would help.

Michael Totten shrugs.
