OPINION — Last week, I lost my composure as I entered the Dulles airport international arrivals area after a transatlantic flight. Scores of Afghan refugees stood between me and the process I had done countless of times – enter the United States after stints abroad, often on CIA assignments. These Afghans were certainly tired, most likely poor, and a huddled mass. Despite the immense challenges many will face integrating into a new society, they represent the fortunate few. Many Afghan allies, including U.S. citizens and U.S. Green Card holders, remain in Afghanistan, along with U.S. Government credibility, if we do not keep pressure on the Taliban to allow them to depart.
