Turkey's president Recep Tayyip Erdogan demanded that the USA should decide between Turkey and Syrian Kurds whom Ankara calls terrorists. However he found himself in rather an embarrassing situation. As it turns out Turkey has been providing all-round support to the militants of Jabhat al-Nusra (recognized as terrorist organization by the whole civilized world) since 2013. That is proved by the circular signed by the minister of the interior of Turkey Muammer Güler. http://www.kuzeyanadolugazetesi.com/konsey-rize-de-golenin-baskani-kayip/449/

It is unlikely that the US intelligence was unaware of the circular before, yet America preferred to keep diplomatic silence when it came to matters of dispute related to national interests. The hot-blooded and short-sighted president of Turkey broke the years-long balance, which may lead to unexpected consequences in relations between Washington and Ankara. It cannot be ruled out that the publication of the circular is a first retaliatory step made by the White House.
