I'm not the one who should provide a source for PKK
not interfering in Syria, but if you think otherwise, you can provide a source that shows big PKK/Iraqi Kurdistan involvement in Syria, maybe there is something that we are not aware of? Anyway, since my post wasn't directed at you, I don't think I should provide a source for you.
About rest of your post, meh... . Btw, this has nothing to do with Iran.
PS: Maybe a good evidence for you is that I haven't found any source proving otherwise, unless you can find one.
