They can't do that when the US literally rescued them from the Nazis & the Soviets...
Western Europe without US backing will be much more vulnerable to Modern day Russia. Which is why they follow whatever the US says.
The Europeans are finally getting their military budgets increased, since threats came from Trumptard of decreased NATO funding...but even then, their foreign policy in regards to the Muslim World will remain the same as that since the 1st Crusade and before...
Going back to the topic....Refugees are one of the most ill treated people around the world...lost their homes, almost no one accepts them...people call them names (even here on PDF) etc etc
While Pakistani & Turkish treatments of refugees have been ahead of the curve and a lot better than what so called "democratic & free" nations of this planet treat them like....we can all, including Pakistan & Turkey, have even better treatment of fellow human beings.
Coming back the US....our treatment of illegal Mexicans is world renowned...it's quite appalling...similar to the treatments of Europeans who bombed Syria to stone age and then killed Syrians who try to come to Europe...
Those Syrians and others living in Europe...that made it....have also seen heightened persecution....especially after a couple of incidents involving alleged refugees.
Either way, it is the responsibility of the host nations, especially in the case of the Euros, to integrate the refugees while giving them breathing space & religious freedom.
That's because you don't highlight it in the media...
I know Islam says to do the good deed and not talk much about it (in the sense of feeling too good about yourself) but in todays age, the Pakistani state, media and the people, must highlight this and spread the news around the world..
It'll show first world nations "how" to treat refugees when they don't even know how to in the first place.
