Mossad vs. the CIA (NIE)

How many US intelligence agencies put together the recent NIE that said Iran had abandoned its nuclear weapons program? 16, wasn’t it? Now these other guys are saying the Iranians will have the weapons in three years. Who do we believe – the folks who weren’t even able to call the downfall the Soviet Union (in fact often said rthe reverse) or the folks who gave the first folks the text of Khruschev’s famous speech denouncing Stalin?
