In the case of the thought process I stated above where the refugees view Europe taking them in as their right and Europe's karma?
Wherever, at that point they will scarcely care. Africa? Middle East? Wherever to get them out of their countries. They can live in an environment more suited to their culture and values if they are trying to totally replace European culture and values.
Such a thought process as I clarified above leads to isolation and acting out. Enough of that can shift the political winds (as we see in Europe today) eventually leading to actions that right now sound horrifying (forced deportation and ethnic cleansing).
to people who say it is impossible, it's happened before in recent history in Europe. It is a horrible evil, but it can happen if a populace with power feels itself justified against a minority.
Its possible, if the political winds don't shift the same way in the US. Muslims here have been more successful in integration, or perhaps the US has been more successful at integrating them? In any case they are not seen as a minority causing problems in the general 'social consensus' (as weird as that sounds) in the US, so the thought of ethnic cleansing or forced en-masse deportations of refugees would horrify at this time. If these immigrants were seen as a fifth column though? Well look at what happened to the Japanese. Sure it was injustice, and yes there were apologies and compensation later, but at the time people were very paranoid, and it happened.
