the fact that you people in europe don't give a shit about terrorism unless it hits you. pkk/ypg are a terrorist organisation who are responsible thousands of civilian casualties, bombings in big cities, killing babies and innocent teachers, medical staff etc. since late 70s. they have been here for about 40 years and you did not give a shit about them. you wouldn't give a shit abous ISIS either, if you weren't affected their actions. US used terrorists to fight the terrorists and fighting terrorists doesn't make terrorists good people. they didn't fight ISIS because they love you so much, they had benefits too.
so, mr. love butterfly, ISIS has been ended and northern syria is/was in control of your so called allies, older terrorists; and we are, unlike you, fighting them for 40 years and we know what they really are, as i said, unlike you. so if you really want to know who PKK/YPG really are, just do some research and you will realise they have no difference than ISIS.
the things you suffered from ISIS, we have been suffering and fighting those for 40 years and you alwys supported terrorists, kept them, did not return bombers, killers and funded them. we are not the bad guys here dude, we're just doing what we did last 40 years. but this time, you can't save those your so called lovely allies, a.k.a. terrorists. this is the reason why you are being so "interested" about middle east.
