So OBL made contact with the U.S. Embassy while in Ankara. What's that got to do with the secular government of the Republic of Turkey? Lee Harvey Oswald contacted foreign embassies while in Mexico City. It would never occur to me to say that Mexico was behind the assassination of JFK. But thanks for the links!
By the way-number of al-Qaeda linked attacks in Greece on Jews? ZERO. Was there not an Muslim bomb attack in Turkey in 1986? Killed a score of people then too.
Turkey may be secular but has no problem in making alliances with those that it thinks will further objectives. Thus the result of letting Turkey serve as a gateway into the Caucuses and into the Balkans and into the Middle East for al-Qaeda comes boomeranging back.
Turkey is know for selling her services to the highest bidder.
