If words were bullets, McGurk would have left nothing alive in the Middle East. The bottom line is that Obama is cooperating with Turkey’s war against the Kurds and is more than happy to see the Kurds hampered in their fight against ISIS. The Kurds have been the only effective and motivated force fighting ISIS and Obama has starved them for weapons and air support.
This has been happening in Turkey for a while now:

I have a pretty good idea how the US would respond if these were your boys that died.
Turkey has a productive relationship with the Kurdish regime in northern Iraq, and is working with the Kurds in Syria as the record shows.
I will respect your perspective, but would hope that you keep an open mind so that we may all one day enjoy a better future together.
