There are other reports placing the origins of the Kurds to far away places than where they settle now, which would explain how they were scattered over a vast area of land over 4 countries with distinctive racial and national sense of identity and history, without a dense and real concentration of the Kurds with proper resources that could be managed and exploited, it'll remain mission impossible for them.

As of now, they're the useful cannon-fodders for the planners and plotters of the crises in Syria and Iraq, they're being prepared to be used against Iran and of course Turkey later on. Many Kurdish militias have committed heinous crimes against other ethnic groups in the land they seek to create their entity on in order to change the demographics of that land. The fact they maintain close relations with Israel through their patrons in Irbil tells a lot about their goals and their roles.

Throughout history, unless they integrated with the communities that welcomed their first migrants like how Saladin got integrated and ruled the whole region, they'll always commit the self-destruction mistakes.

They're in a landlocked region and their dreams of exporting any goods or importing it will evaporate once their neighbors Iran, Iraq, Syria and Turkey seal them off, thus strangling them legally to non-existence as an entity.

The elders of the Kurds and the wiser ones of them should immediately make a move to stop their collective suicidal mission before the end of the war of terror in Syria and take the right decision of re-integrating within the communities they preside before the losers of the war of terror in Syria have to pay the price by getting evicted and dispersed. This is not a threat, this is how history works: Victors write it and fix the ground based on their writings.
