What are the different Kurdish militant groups?

Answer 1

The Kurds are not completely internally united and are actually made up of three main groups:

1) The PKK paramilitary/terrorists in Turkey;
2) The YPG, an offshoot of the PKK, in Syria;
3) The union between the PUK and PDK in Iraq.

This division results in difficulty between coordinated attacks from Kurds in Iraq in Syria or in defense of the PKK in Turkey, which is under attack from Turkey. Given that the PUK and PDK use Turkish military intelligence in targeting ISIL, the PKK has become suspicious the PUK and PDK know about impending Turkish attacks against their organization and are failing to provide advanced warning. YPG acknowledges that PUK and PDK are stronger militarily than it is, but it does not want help from the PUK and PDK to translate into political or administrative power at a later point in time and is wary to accept military help for that reason. The Kurds collectively maintain good relations with both Iraq and the FSA, since those groups have made provisions for Kurdish autonomy or independence. They jointly coordinate attacks on ISIL or Syria with these groups. The YPG is direct conflict with both Assad in Qamishli and ISIL further south, near Deir el-Zour, and further west, near Kobane. The Kurds collectively revile ISIL for its barbarity as well as its genocide against Yezidis (who are all ethnically Kurds) and Assyrians (who the Kurds consider "their guests" in Kurdistan). The Kurds are the most successful Anti-ISIL group currently fighting.
