Today (Tuesday, July 14), representatives with the United States and other world powers reached a historic agreement with Iran's leaders that calls for limits on Tehran's nuclear program in return for lifting economic sanctions that have crippled Iran's economy. The agreement, which is aimed at averting the threat of a nuclear-armed Iran and another U.S. military intervention in the Middle East, is the result of 18 days of negotiations.
