This document summarizes the views of Dr. Peter Hammond on how civilizations can commit suicide through mass Muslim migration and multiculturalism. It discusses how Christianity was eliminated in Egypt, Turkey, and Northern Sudan as Muslim populations grew. It warns that Europe could face a similar fate and lose its Christian identity if current migration trends continue, as Muslim populations grow and seek to impose their culture and religion. It argues the current migration crisis has been artificially manufactured to irreversibly transform Europe's ethnic and religious composition.
