The old paradigm that a country has the right to decide who enters it has been decisively overturned in Europe, it's under siege in such first world countries as America, Canada, Australia and Israel by the creed that says it's the human rights obligation of every nation to accept every refugee.
Given a chance a sizable portion of the third world would move to the first, a minority because of oppression and a majority because the opportunities and freebies are much better there. Even low ranked first world nations still find themselves swamped with refugees looking to move in.
International law does not assign any priority to a nation's citizens over any person who happens to stray across the border. At the ground level that means the end of borders and the end of citizenship which is why immigration isn't just a touchy issue in Arizona, it's a touchy issue in Sydney, Tel Aviv and Birmingham. You can hardly open a newspaper of the liberal persuasion without being treated to another group of refugees in some troubled part of the world walled up behind fences and trying to get over to London, Sydney or New York.
This sort of thing can't be called immigration anymore, it's a straightforward migration and it has no apparent limits. However many you take in, there will be more waiting and always burdening you with an unsolvable crisis.
One approach is to try and stabilize whatever crisis they are supposedly escaping from. Too many Libyans running away to Italy? Just bomb their dictator and they'll go home again. At least that's the theory, it doesn't work too well in practice. For one thing Libya is more dangerous and unstable than it was under Gaddafi. Stabilizing it would require an Iraq level investment of money and manpower, and Iraq isn't stable either. And London is still full of Iraqi refugees dating back to the 1980's.
The disparities that make migration aren't fixable, but nor is mass migration a viable option. There's a reason that the refugees are running away and they are often part of the problem. Every nation is troubled in its own way and mass migration imports those troubles. It's why beheadings have come north of the border and the Jihad has set up shop in countless Western cities.
The melting pot myth was that people leave their identities behind to join in a mass identity. That worked only marginally back in the day, it doesn't work at all today when the refugees are immersed in their Little Mogadishus, which have popped up in a frightening amount of American cities foretelling the day when those cities will become as violent and broken as the original Mogadishu.
In place of the melting pot is the No Go Zone, which is the inverse of integration, it sets up tribal encampments in major cities which run on the laws of the tribe. That sort of thing has always been around in one form or another and it is survivable in limited numbers so long as those zones don't also become factories of violence. That's the difference between Amish Country and a Muslim banlieue, it's also the difference between separatism and supremacism.
This is a good analysis of why Islam is being used by the globalists / internationalists / statists who would erase borders and subsume the nation state into the NWO.
Zitat. . . They [Moslems] are better adapted to the end of the state, because they have never truly internalized the reality of the state, than the Westerner for whom the state has become the fundamental unit of existence.
Westerners have become the ultimate refugees, lost at home, refugees in their own countries, wanderers in their own cities. The same processes that have turned their countries into superpowers are now drowning them in their own effluvia. And the citizen of the first world often finds that he seems to belong less in his own country than the refugees flooding it. He has become a displaced person, a familiar enough feeling to many of his new neighbors who are also victims of ethnic and religious conflicts. But while the conflicts they have fled are official, his conflict is not. He is the victim of a nameless conflict that cannot be named, of a colonization that cannot be described as such and of the ethnic cleansing of his national identity and the theft of his future.
