First question: Did the U.S. use the kurds or did the kurds use the United States of America.
We armed them in their battle against area Christians. We carved out a very large portion of Syria and got the Russians to look the other way. And, that portion of Syria holds over 65% of all of Syria's oil and gas reserves. Moreover, it is one of the few agriculture rich areas of that nation.
We did far more for the kurds than the kurds could even DREAM of doing for us.
Look into the situation. Study the situation. You'll see it that way ... because that's the truth.
