"What Turkey is going to do is unleash holy hell on the Kurds. In the eyes of Turkey, they're more of a threat than ISIS. So this decision is a disaster." — U.S. Senator Lindsey Graham.
The U.S. move also could turn out to be a death-blow on Washington's efforts to keep Tehran from further establishing itself in Syria and threatening the security not only of Israel, but of the entire Mediterranean region.
Potential Turkish-Kurdish conflicts would further destabilize Syria and strengthen Russia. This point cannot be ignored. Turkey's and Iran's dependency on Russia in Syria will increase, as the trio further teams up to have a larger role in shaping Syria's future.
It is understandable that abstaining from the role of the world's policeman may look consistent with Trump's pre-election pledge to "Make America Great Again." Nevertheless, caution is needed here: Leaving the "policing" job in the world's most volatile and turbulent parts to un-free regimes such as Russia, China, Iran and Turkey could also damage the quest of America and others in the free world to become great again -- and to remain free. The free world simply does not have the luxury -- even in remote geographical areas -- of allowing security to be policed by un-free state and non-state actors.
