Free Trade in an Age of Terror

The war on terror appears to be causing a surge in protectionism. Some anti-terrorist warriors are so worked up about immigrants that they want to build a wall along the entire United States-Mexican border. They also are fighting the proposed takeover of US ports by a Dubai company, because they fear terrorists could gain vital intelligence from the investments. In Europe, the movement to stop inflows of migrants from Muslim countries is extremely popular.

These developments do not constitute more protectionism in the usual meaning of the term, where private interests subvert the public good, as when farmers charge higher prices because competitive imports are restricted. National security concerns are not foolish. While a nation has a clear interest in the benefits of free and open trade, it also has a vital interest in its citizens’ safety.
