There's lots to wonder about in the Key Judgments of the latest National Intelligence Estimate, which informs us with "high confidence" that Iran halted its nuclear bomb program four years ago. This contradicts its 2005 warning that Iran was "determined to develop nuclear weapons." That followed the 2003-2004 zig-zag from our intelligence community on Iraq and Saddam Hussein's interest in weapons of mass destruction; which followed the intelligence failure to zero in on the Sept. 11, 2001, hijackers before they slammed airplanes into the Twin Towers, the Pentagon, and a field in Pennsylvania.
