The US would do well to help that happen.
Which is why we need to stop claiming we are keeping troops there and keeping the Syrian oilfields to protect them
From the govt of Syria
Assad now has the dominant military ground force in Syria, especially with the Russian support.
We need Assad and the Syrian Kurds as a check against Turkish imperialism and a check against Iranian aggression against Israel and as a check against the remaining AQ/ISIS/salafist jihadists.
But the Kurds are poor and need much more training and military hardware and military bases. They need armor and artillery and helo assault forces.
If we can hold onto the Omar oilfields for them, the Kurds can afford all that.
