why the US wants to establish Kurdish state in eastern parts of Turkey ?

Well I don't have nothing against you or your people, but you cannot ignore the history. As I have mentioned a thousand times about the land Kurdistan. I am very sure that generations after generations of Kurds knows about their past history, and of course they want to establish their lost identity.

I am not a Kurd but I know what happened to their homeland just by reading and searching their history. And I cannot blame you for loving your country. Everyone should, but we cannot just ignore and turn a blind eye of what happened in the past. It is not your fault what happened, why it happened, and turning your back and not accepting the truth will never solve a problem. I am very sure that you understand what I mean.

They can put pressure on Turkey to create a Kurdish state like the one in Iraq I suppose. That way the U.S. can control the Kurds who are beholden to the U.S. for creating the no-fly zone keeping Saddam out of northern Iraq and protecting them so they could develop their own economy with U.S. money. It is just a misguided notion of some American officials to remake every country in the image of the U.S. by taking away the sovereignty and nationalism that exists in the Middle East because they also believe that patriotism leads to terrorism against the U.S. Thats what i think. As an American resident who is poor I don't want the revenues going to any more nation building in the Middle East. It wont change the reason people hate the U.S. government.

"Kurdish identity is not pure identity that mixed Turks"

This is a nonsense claim. You cannot make an ancient people disappear just by pretending that they're the same as the Turks.

Your government committed mass murder and genocide against Kurds, Armenians, and Anatolian Greeks. And instead of recognizing your own mistakes, you compound them by denying that they ever happened.

The identity of the Kurdish people is determined by THEIR sense of common identity. Not by yours. You have abused your Kurdish population enough. Because you cannot be trusted to deal fairly with your ethnic and religious minorities, you don't deserve to have them. It would be good and just if a Kurdish state were finally carved out of eastern Turkey, Northern Iraq, northeastern Syria, and southwestern Iran.

Turkey is more like an empire than a country, and genocides have occurred in the past to weed out the less subservient ethnic cultures. It's no wonder the Kurds, who predate their conquerors by thousands of years, want to be free of it.

No source, you lie
