The membership of Turkey in NATO means more than you think; Actually how the USA sees it was described in the Reagen diaries. Obviously you are not aware of that diary, but we are.
I am sick of that song of money flowed into Turkey; You should check out how much money( billions of dollars) Turkey has lost since the first gulf war, plus refugee problem, plus PKK terrorists's safe heaven in Iraq for attacks to Turkey, plus destabilization in southeastern Turkey in respect to social, economical and industrial aspects.
If we start to compare the lost of Turkey with the aid of USA, You would be ashamed of bringing it on the table and making an argument out of it.
as for the thread, USA seems in a policy-shifting in the region even though Kerry claims otherwise in phone call with Erdoğan. That move of helping terrorists in Ayn Al-Arab is actually a historical and strategical move compared to action which is a small step.
USA officially recognises PKK as terrorist organisation but she supports a branch of it in Syria. USA is now sponsor of terrorism, and rough country. she supports a terrorist organisation that does attack and kill people of an ally country that recognises them terrorist.
That is very sad. That was not worth it.
