Will Hispanic Population Explosion Divide the U.S.? In an essay in Foreign Policy magazine, renowned academic Samuel P. Huntington argues that Hispanic immigration threatens to divide the United States "into two peoples, two cultures, and two languages." Some immigration-reform groups are taking heart from this theory. But Latino organizations are both furious and baffled over this assertion. We hear from Ira Mehlman of the Federation for American Immigration Reform, Lisa Navarrete, vice president of La Raza, and Clarence Lusane of the School of International Service at American University.
