Iran continues to refuse to disclose its nuclear activity, and experts do not anticipate the country will become more transparent in the future. That’s the assessment released Friday from the International Atomic Energy Agency. “The agency is not in a position to provide credible assurance about the absence of undeclared nuclear material and activities in Iran, and therefore to conclude that all nuclear material in Iran is in peaceful activities,” said the report, which was also pessimistic about the chance that Iran will be forthright with its nuclear activities in the future. The report notes that Iran has not “proposed any new practical measures in the next step of the Framework for cooperation.” President Obama recently wrote a letter to Iran’s supreme leader asking for help fighting ISIS in exchange for a deal to resolve the nuclear standoff.
