"In the face of the ISIS sweep, the [Syrian Kurdish] PYD and the KRG, which [like the PYD and Turkey have] antagonistic relations, [but] appear to be cooperating on defensive measures against ISIS." This new situation may even lessen the antagonism between the PYD and Turkey.
I believe that Washington supported these ISIS things against Assad. And so did Turkey. Turkey has financial interest in the KRG. Below is how Turkey like us must now oppose ISIS.
The KRG is NOT the Kurdish PKK terrorist that's been fighting Turkey since the 1980s and trying to stir revolution in eastern Turkey.
This has some interesting information about the current events in Iraq. IMO.
". . . Ankara has entered into energy deals with the Kurdistan Regional Government (KRG), something which has infuriated the central Iraqi government in Baghdad but which has helped the Kurds further build a foundation for their independence [yes true that] Ankara has been so alarmed by the growing Kurdish autonomy [in Syria and tolerated by Syria, I believe] that it reportedly has provided support for [ISIS] in their fight against the Kurdish militia that controls the region [of Syria],which is affiliated with the outlawed Kurdistan Workers' Party (PKK)."

". . . the takeover by ISIS in recent days of Mosul and other cities . . . Ankara will likely not only have to deepen its relationship with the KRG . . . but also alter its approach to the Kurds in Syria [I ask: but demand that the Kurds in Syria reject the PKK?]"

"Explains Lehigh University professor and Turkey expert Henri Barkey in an analysis piece on Al-Monitor website: The crisis may force the Turks to rethink some of their policies in Syria. To date, Ankara’s friendship with the Kurds stopped in Iraq; Erdogan and his government have taken an uncompromising position against Syrian Kurds led by the Democratic Union Party of Kurdistan (PYD), an offshoot of the Turkish Kurdish insurgent group the Kurdistan Workers Party (PKK). The PYD has emerged as the strongest Kurdish group in Syria and has put together an impressive fighting force to defend its territory from both ISIS and the regime. The idea of another autonomous Kurdish region on its borders after the KRG has been anathema to Ankara. Paradoxically, the PYD’s armed elements are some of the only ones that have scored blows against the jihadists. In the face of the ISIS sweep, the PYD and the KRG, which have also had antagonistic relations, appear to be cooperating on defensive measures against ISIS. Turkey may have to reconsider its boycott of the Syrian Kurds to enlarge the anti-ISIS coalition." [my emphasis]
Perhaps Turkey is about to become bright spot of sanity in the region. Is doubtful Washington will wake up though ... and you are correct ... obama and his crowd are invested heavily in isis.
oh forgot to add ... the saudi royals and qatar are invested heavily in isis also. obama is a sunni. No doubt at this local.
