The Trump action prohibits travel to the U.S. for 90 days for citizens of seven predominantly Muslim nations, halts refugee admissions for 120 days and halts Syrian refugee admissions indefinitely. It was not in reaction to a specific incident. It went far beyond one country. And it's a ban. The 2011 action didn't, for example, affect refugees; it was a matter of slowing, not stopping, travel from the one country where there was a threat. And finally, the 2011 action wasn't done haphazardly. It was reviewed by multiple agencies including the intelligence community. There was no sudden reversal of airport traffic and threats of deportation of children. It also took place at a time when vetting was less thorough than it is today. (Now refugees, for example, may have to wait years to qualify for entry.)
