Some bold and simple policies have merit; Friday’s executive order that temporarily bans the citizens of certain countries from coming to the U.S., and stops indefinitely the entry of Syrian refugees, is not one of them.

As designed and implemented, there are genuine doubts about the order’s effectiveness in meeting its stated objective of preventing terrorism. It also risks a lot of collateral damage and unintended consequences that ultimately could prove counterproductive and harmful to national security, the economy, and America’s moral authority, values and standing in the world. Even the order's merits as a domestic signal are in doubt, and it risks damaging the credibility and effectiveness of future policy initiatives from the White House.
