European leaders are declaring the failure of multiculturalism.

French President Nicolas Sarkozy on Thursday declared that multiculturalism had failed, joining a growing number of world leaders or ex-leaders who have condemned it.
"We have been too concerned about the identity of the person who was arriving and not enough about the identity of the country that was receiving him," he said in a television interview in which he declared the concept a "failure."

British Prime Minister David Cameron last month pronounced his country's long-standing policy of multiculturalism a failure, calling for better integration of young Muslims to combat home-grown extremism.

German Chancellor Angela Merkel, Australia's former prime minister John Howard and former Spanish prime minister Jose Maria Aznar have also in recent months said multicultural policies have not successfully integrated immigrants.

America has been encouraged down this road of identity politics too. For 200 years a guiding principle of this nation has been assimilation. E Pluribus Unum - Out of many, one. Then the multi-cultists went to work on college campuses and into government, stressing the importance of ethnic, religious, racial and sexual identity. It is and has been a divisive and often ugly project.

Old-fashion liberals understood multiculturism's perniciousness. Arthur Schlesinger Jr. wrote the Disuniting of America back in 1992. Not surprisingly, it received negatives reviews from far leftist professors committed to the idea that America was worth disuniting. It could use a re-read.
