"If this can be solved it can only be solved through Turkish efforts."
Veysel Ayhan, an associate professor from the Bolu Abant İzzet Baysal University and an expert on the Middle East and Syria, said a NATO intervention in Syria would turn the region into absolute hell. “Turkey is back to its position in the 1990s. It is pursuing a proactive foreign policy. We can confidently say that a wave of refugees much bigger than the one during the Gulf War is in store, as it is unlikely that the situation in Syria will be resolved in the near future. NATO handled the situation in Afghanistan and Libya badly. Western countries can't make any contributions to NATO in similar operations. If this can be solved, it can only be solved through Turkey's efforts. If, in the long run, NATO intervenes, we could be faced with a more dire picture.”
weapons. Syria has another problems namely if its forces came up against the superior Turkish military, purportedly there to protect the Sunni majority from the Alawi minority dominated state, there is likely to be a level of defection by the Sunni dominated lower ranks.
If Turkey believes it needs additional forces it is preparing for the potential of a regional war (* perhaps it is just overkill).
Key Points on regional war;
If the Syrian regime falls to fast Turkey would be all but required to occupy it for its own security and to prevent the humanitarian catastrophe that would unfold.
Pluses for Turkey intervention militarily
If there is to be an operation in Syria the Turks appear to want to go it alone (visibly at least… NATO satellite, deterrence, and anything else they need will be there). The Turks would be the protectors of the Sunni Islamic World. Reestablish some of the Espri de corp the military has lost lately while shoring up civilian control. (Not much)
Negatives
Of course intentionally risking a regional war would be foolish. Turkey already feeling the financial losses do to the disturbances in the region, the inflow of refuges, the effect on the Kurdish insurrection, its relationship with Iran being damaged, the effect of its image on the Arab street will likely divide Shia Sunni rift, a lot of people could/will die, outcome of the conflict will be even less predictable, and potentially a major shift in regional power from Iran to Saudi Arabia (chose for yourself if that's any good).
So lets hope for a serious diplomatic effort works because as Michael Bell wrote (in one of the more intelligent pieces out) 'There is no happy end to Syria's power struggle. Hope your up for a challenge Prime Minister Recep Tayyip Erdogan and Minister Ahmet Davutoğlu because as was stated Only Turkey can do this. We hope you chose the wisest course and We wish you the best.
For an understanding of the sectarian problem Josh Landis's blog "Syria comment" has a blog it's a bit of a collection of news but there is first hand account of the radicalisation of Syrians from somebody in Syria about the radicalization on the minority communities. I can't find it try yrself.
