I'm aware the group claims not to be so, but the fact is they and those that support them are. This movement we see here is a Kurdish nationalist movement, and as Osman Ocalan (brother of Abdullah Ocalan and former PKK member) said in an interview:

NIQASH: Do you think that the PKK wants to be seen as the leading power in all of the parts of what would be Kurdistan – that is in Iraq, Syria, Turkey and Iran – if Kurdistan were an actual country? Ocalan: Yes, the Party wants this. It works with centralised power so for that reason alone, it doesn't believe that any other political forces should be present. It wants authority in all four parts of [what would be] Kurdistan. When they talk about unity and nationalism, they only mean that everybody should belong to the PKK.
