I watched the Glen Beck show last night and it was fascinating. Even Beck said he thought he was sounding like a nut case but the date Aug 22 was looking more and more like a date to start something big. He surmised that the airplane plot was to cause distraction while Iran was plotting something big.
Aug 22 was written about in the Wall Street Journal by Bernard Lewis who Glen Beck kept referring. The article is linked to below.
