Muslims will conquer Europe by migration and demography

This seems to be the message of  Houari Boumediene, President of Algeria, who said at the United Nations in 1974: 

One day, millions of men will leave the Southern Hemisphere to go to the Northern Hemisphere. And they will not go there as friends. Because they will go there to conquer it. And they will conquer it with their sons. The wombs of our women will give us victory.
