During his inaugural address, Donald Trump vowed to "completely eradicate" radical Islamic terrorism. Today, in its first moves intended to do that, the administration acknowledged its plans for a complete ban on immigrants and refugees from several majority Muslim countries, including Syria, Iraq, Iran, Libya, Somalia, Sudan and Yemen. Yet the new policy will work contrary to its goal. U.S. Muslim immigration is reducing radical Islamism and anti-Americanism around the world.
For President Trump to fulfill his promise, America will need to do more than kill terrorists and arrest their collaborators. It will need to change the minds of many Muslims around the world about America and its institutions. Immigration is the best—perhaps the only—way that it can do this, and right now, U.S. Muslim immigration is reforming the religion, creating a new cohort of liberal Muslims able to combat Islamist arguments.
