You can. A million people sounds like a lot, but the EU has 550 million citizens. It's a matter of redistribution. The Netherlands currently has 1,8 million people that have non-western origins. The largest problem we have is Geert Wilders.
How we distribute them throughout Europe is one thing. The problem is that the immigrants are not eager to be "redistributed". They focus on the most generous welfare states like Germany and Sweden. If you force a group of them to settle e.g. in Poland, most of them would soon depart to Germany.
Which is why, as MP-Ryan already mentioned, we need to handle this at a federal level.
Second thing is how we treat them. They are mostly placed in camps where they live among their brethren and therefore feel no need to assimilate. As they receive social benefits, they don't need to work either.
I am not sure how it is over at you, but refugees that are placed in dutch detention camps do not recieve benefits. To recieve social benefits you have to be a dutch citizen, and the refugees that are placed are not: They are waiting for the completion of the process that will indicate if they get a shot at becoming a dutch citizen or not. That this is a process that can take years is a problem. A similar and related problem is the process that refugees in The Netherlands have to go once their refugee status has been denied, which takes so long that people have been driven to suicide over it.
What is more, police and authorities are given instructions to tolerate visitors' assaults on women and other violations of law. If you send them a signal "we won't punish you", then how could you expect them to change?
Where did this happen?
Oh just about pretty much in all the larger cities that have districts in the hand of large arabic families, Berlin Neu-Köln probably being the most prominent example. To be fair, catching people giving actual instructions may be rather diffcult, but there is definitely a huge willingness to self censor and give people with immigrant backgrounds huge leeway in order to avoid being called a Nazi. If this willingness is a case of common sense and self protection or if it's an actual order from a superior is a rather moot point however imho. The effect is pretty much the same ...
In addition to molesting of women and aggressive pickpocketing of anybody else in certain districts of larger cities ...
You have cases like a father raping his daughter and being set free by the German justice system because persecuting the case would mean the victim would be revealed as "dishonored" to her entire family and hence become the victim of a "honor killing" before long.
You have countless cases of socalled "justices of the peace" applying Scharia Law in cases where both parties are Muslim and once and agreement is reached all the people involved suddenly forgot what happened in front of the German judge.
You have reported cases of the larger families with criminal inclintion deliberately "importing" 12-13 year old children from abroad in order to use them for criminal activities before they turn 14 and can effectively persecuted by adult law.
If you want to catch up on those issues then "Das Ende der Gedult" by the Neu-Köln judge "Kirsten Heisig" would be a good start .... and keep in mind those cases i named above are all already 5 year old ... but every single one of them a testament of utterly failed integration of people adhering to hardline Muslimic culture.
Heck ... if you check out Tanja Kambouri's "Deutschland im Blaulicht" it paints a pretty grim picture of the treatment of female police officers on duty. Starting with utter disrespect and gratuitous power games going up to actual assault.
Then you have the whole mess with Cologne this year that made it so obvious how police and media tip toed around the issue of immigrant crime, everyone being oh so afraid that no one call them Nazi for suggesting not everything is "just great" with all those people coming in. Well, that mess at least was too big to not keep talking about it. But the local media is still full of smaller cases of sexual assault and petty theft that isn't even persecuted anymore simply because there is so much of it and there are no consequences that would deter the perpetrators.
Now don't take me wrong ... right extrimism and the violence it causes is a huge problem. But it is only one problem of two. Failed integration, unwillingness to integrate and crime rate amongst immigrants and refugees, especially amongst those with arabic muslimic/patriarchalic back ground is the just as big of a problem if not bigger and if that wasn't bad enough.... the failure to deal with the later problem, no wait ... the absolute unwillingness to even properly address it to the point of aggressively defaming anyone who even mentions immigrant crime over the last year(s), is naturally making the former problem of right extremism even worse as well.
Or in other words: The politic landscape in Germany isn't really a total clusterf*** right now because of the "immigration crisis" ... rather it is a total clusterf*** because of years of failed integration policy of pretty much all the major parties (Reds, Blacks and Greens just alike, if in different ways) and an exaggerated sense of political correctness resulted in attacks on anyone who suggested there even is a problem. (and again, that goes for the last years, not just the immediate crisis.)
What the current influx of refugees did however, was pretty much make it obvious just how badly integration policy is working. Or rather, and yes as sad as it is that kinda is the whole issue: How bad integration is working with people with arabic/muslimic backgrounds. There are no integration problems with Italians, Greeks, Spanish, Chinese, Japanese or whoever else. There is however a huge issue with people of the Muslimic inclination, or rather, to be more precise, with people of a conservative/literal Muslimic inclination, up the point where several of the Muslims who live in Germany for years already and are well integrated are shaking their head in disbelief at how politicians and the justice system are dragging their feet.
(And yes ... there are also cases of critical/moderate and well integrated Muslims being attacked by German Media as "Muslim haters" or "Islamophobes" just because they actually addressed the violent and mysogynistic tendencies of Muslims who follow a more conservative/archaic interpretation of Islam and wanted to discuss solutions - at the same time the same critical Muslims receive death threaths from said Muslims of a more archaic inclination - would be hilarious if it wouldn't be so serious and also showcase how FUBARED the entire public discussion of the matter is.)
As mentioned above, Kirsten Heisig's book would be a good starting point if you want to read up on what I addressed in this post.
