Not to spoil it, but because this is SLL, and SLL is generally anti-interventionist you can probably guess that the correct answer is the last choice: just plain stupid. From Michael Scheuer at theburningplatform.com:
As can be seen, there are substantial Kurdish populations in Syria, Turkey, Iraq, and Iran, and, at least in Iraq, Kurdish territories sit upon enormous oil and natural gas reserves. Each of those four nations has long feared the Kurds’ strident demands for an independent Kurdish state, their fighting abilities, and their fiery nationalism. As fear always does, the nations’ fear of the Kurds has led to their economic, social, linguistic, and – at times — military oppression by each government. In short, Syria, Iraq, Turkey, and Iran have long seen their Kurdish populations as malcontents bent on independence and so a threat to their territorial integrity.

The powers that be will abandon everyone in this equation of bloody insanity when it becomes politically expedient sure as the sun rises.
It is political expedience for the purpose of more power and more wealth that drives it to begin with.
For they have no fealty or loyalty to none other than their greed and power.
For how could they, they abandoned the dirt people of America in 1862 and never looked back, millions dead and entire civilizations mean nothing, only as instruments to further wealth and more power.
