Iran announced it has enriched uranium beyond the 3.67% limit set by the 2015 nuclear deal. This comes less than two weeks after it also increased its stockpile beyond the 300 kg restriction. The country says it hopes to prompt negotiations for relief from heavy U.S. sanctions. Trita Parsi, author of "Losing An Enemy: Obama, Iran, And The Triumph Of Diplomacy" and the executive vice president of the Quincy Institute, joins CBSN with his analysis.
