I don't think the PKK in general likes the Jews. Maybe i'am wrong?
I saw many that do, but even if they don't its not about love its about what is tactically in our benefit. It could even be that Israel maybe should support the Baluchis in Iran although they would and do have absolutely no love for Israel, but if they could be helped to fight harder against Iran then even more so better. They support terror against Israel, Israel should support terror against them.
