Politico reported that the president of Colombia refused to allow U.S. military aircraft to land; the two airplanes were carrying immigrants who had been detained. Trump immediately slapped a 25% tariff on all goods imported from Colombia to the U.S. He threatened that the tariff might rise to 50%.

More than a quarter of Colombia’s exports are sent to the U.S. The two countries have a free-trade agreement.

I am not an economist but I wonder: If Trump damages the Colombian economy, won’t that encourage more Colombians to enter the U.S. illegally in search of work?
