This would be good news if it turns out to be true:

A former Iranian deputy defense minister who once commanded the Revolutionary Guard has left his country and is cooperating with Western intelligence agencies, providing information on Hezbollah and Iran’s ties to the organization, according to a senior U.S. official.
Ali Rez Asgari disappeared last month during a visit to Turkey. Iranian officials suggested yesterday that he may have been kidnapped by Israel or the United States. The U.S. official said Asgari is willingly cooperating. He did not divulge Asgari’s whereabouts or specify who is questioning him, but made clear that the information Asgari is offering is fully available to U.S. intelligence.
