Iran releases four American prisoners!

[True Federalist (진정한 연방 주의자)]

Sadly, Robert Levinson hasn't been released.

That would require Iran to admit they're holding him.  They won't do that until the U.S. admits he's a CIA agent, regardless of whether he's actually one. We won't do that, regardless of whether he's actually an agent. Unfortunately, I think the best the Levinson family can hope for is that when he dies, the Iranians "find" the body and return it the U.S. for burial.
