After reading this article, you might want to send a thank you note to the State Department. In the 1990s, they arranged the entry of some 80,000 Somali "refugees" into the US. Two of the largest resulting Somali communities became Minneapolis and Nashville. Assimilation has been an abject failure. Youth gangs have been born, and many have returned to Somalia to join the terrorist/jihadist organization, Al Shabaab.
And that is not all.
And the flow continues.
