Trying to bring all cultural's of the world under one banner, the banner of Multi-multiculturalism is a fools errand. Many groups in the Middle East would like to migrate to Europe or America is search of a better way of life. That said, these immigrants do not want to embrace the values of the country they move too. They instead, would find their way to neighborhoods where like-minded individuals live. In short, they would not assimilate! It is estimated that some 5% of the worlds 1,000,000,000 Muslims are sympathetic to Islamic Terrorist. That comes out to about 50,000,000 who support terrorism is some form. Donald Trump as well as Ted Cruz have it right, for now we must stop Muslim migration to this country less we let in those who would seek to bomb and kill the infidel---that's us!
