and this standard procedure is carried through with? and applied?
Honestly do you have anything to back this up with? Not necessarily with this current migration even, but with fairly recent previous migrations. Such as the Balkans wars. Did any of them return? because if they didn't I can't see anyone from sub Saharan Africa being sent back, ever.
People are being "repatriated" all the time after their applications are denied. Why do you think countries would even bother with an application process if it's actually meaningless? What happens is police escort them to the airport, puts them in an economy seat and sends them on their way. Easy as that.
They aren't picky either - if there's any chance a person can be repatriated (which is pretty much always, with an exception being a very small number of people no country will accept) they
will repatriate them. I've personally seen a man who's application was denied who was being examined for a lung disease. Once Tubercolosis was ruled out the immigration police determined him "fit for travel" despite the fact that he could barely breathe (fit for travel essentially just means you'll survive the journey) and sent him off to whatever east African country he was from. We figured he probably had late stage lung cancer but weren't allowed to investigate it further. I doubt he even survived a week in whatever country he ended up in.
Universal quota of what? Why would a fair quota mean taking millions? The entire point of the refugee system is that it places burden on the neighbours, this is not a new fact that sprung up out of nowhere. When you sign the UN refugee stuff you agree that if your neighbours get into trouble you will take them in. So it is right and normal that the vast majority of the strain should be borne by the neighbouring countries and then we can assist with any extreme overflow.
Universal quota as in you apply for asylum in the EU rather than in a specific member country and the EU then decides which country will take you in. It's the only solution that allows the Schengen treaty to remain in place and what the EU has been discussing all week.
It's only fair that the EU, population 500 million and largest economy in the world, take a greater responsibility for this disaster than the neighboring nations that are much smaller and much poorer. And no, the UN refugee treaty is not limited to just neighbors, it states that every country has a responsibility grant asylum to anyone who fulfill the requirements for it. And even your "extreme overflow", which is causing the problems in the quoted stories in your post - because Turkey and Lebanon can't possibly take in millions on their own and grant them any kind of future - will be in the millions because there are millions of refugees. 4 million have already fled. Another 8 million could leave Syria at any moment. This is reality.
