This contradicts my analysis of a Turkish foreign policy change moving from a solely western orientation towards a more eastern one. Such a change implies a less intense Turkish engagement in Syria.

Earlier reports by the Economist and the Financial Times pointed to less active role of Turkey in Syria. But a new Financial Times piece (Textcopy) emphasizes the role of Turkey in supplying and training various oppositions groups, especially al-Qaeda, while minimizing U.S. involvement:

[T]he offensive against President Bashar al-Assad's troops may have had more foreign help than it appears: activists and rebels say opposition forces were replenished with new weapons, cash and other supplies before and during the fighting.
