75% of Kurds are Sunni Muslims. The Kurds have been at war with Turkey for a long time, most of Turkey is also Sunni. This is a ethnic tribal war that's gone on for a long time.
It's a chitfest we don't want to get in the middle of. The Kurds are only our friends because we supported their cause, which is a Kurdish country.
We armed them, we financed them, we advised them... for their efforts to defeat Isis.
Isis is defeated.
End of story.
