The Arab Spring rebellions, plus several ongoing nations with serious internal problems, led to a record 33.3 million people being forced from their homes in 2013. Over 60 percent of these refugees were in just five countries; Syria, Colombia, Nigeria, Congo and Sudan. That’s 16 percent more refugees than in 2012. The increase is largely driven by the Syrian government strategy of deliberately targeting pro-rebel civilians and the Islamic terrorist campaign against non-Moslems and pro-government Moslems in northern Nigeria are doing the same thing. Worse yet, decades of monitoring these refugees shows that, on average, these refugees spend 17 years as refugees once they are driven from their homes.
The UN is under pressure to do something about the post-World War II tendency to allow displaced people to remain refugees for decades, instead of persuading host countries to just absorb them. That is how refugees were handled for thousands of years, and how Europe and China handled over ten million refugees after World War II. Then again, until quite recently it was also quite common for large numbers of unwanted refugees to simply be killed.
The more recent practice of maintaining refugees for decades has led to more terrorism and violence in general. The treatment of the Palestinian refugees is the most vivid example of this policy. The equal number of Jewish refugees expelled from Arab countries in the late 1950s was absorbed into Israel and Western nations and were never a problem. The Arab nations refused to absorb the Palestinians and insisted they remain refugees, which millions do until the present. This has caused or contributed to several civil wars and terror campaigns and the deaths of thousands of people.
The UN has had a difficult time getting countries, especially those outside the West, to absorb refugees. It’s mainly an economic, cultural and political thing that is at least made tolerable by all those UN refugee camps (paid for by Western nations).
