A new study published this week by the National Iranian American Council argues that the various trade sanctions the United States has maintained on Iran for more than a decade actually hurts the American economy. The NIAC, a U.S.-based organization that pushes for a peaceful resolution of differences between Washington and Tehran, calculated that between 1995 and 2012, the United States has forfeited between $135 billion and $175 billion in export revenue as a consequence of not doing business with the Islamic Republic.
