You have to understand that for us that don't live in Middle East, we see YPG as a good guys that fought against ISIS. ISIS were bomb attacking in Europe. So you should understand that whole Europe media are against you. I can imagine that YPG are terrorists also and I don't want to sound like egoist, but that's your problem, NATO can't attack anyone that one of their members calls terrorists, NATO is a defence system party. If you would release your refugees I'm sure EU would secure schengen area by police and military, of course a lot would pass, but a lot would not. Also I think if you would release them and it would cause terrible problems to Europe, at the end of the day, it will be you that would suffer more. Schengen border states would have to exactly as you do, invade other country's land, sanctions by EU,USA... etc. etc, and it will be supported by whole Europe because of that mess beeing made by you. Politics of fear is nothing that I would ever support.
If we talk about money, I think 6 bilion was promised and 3 already was paid. If you pay more money that can be also your rigged system of supporting those refugees, just sayin. Lower their standards maybe.
If I would like to see them in my country ? Definitely not, but at least, my country is 100% against reception of refugees. Well, European government is almost the same as in every country.... useless, so don't expect something useful.
So at the end of the day, I possibly can understand, you invading Northern Syria, but your strategy is just making terrorists of you all... and btw what about that murdered politician.
