Fun article, but Martin Armstrong should be filed with Alex Jones - a lot of good info but ultimately comped. You know the score - 90% good stuff, but the other 10% disinfo keeps you away from the really interesting things. The article suggests that he knows about 9/11 being an inside job, but his actual view is that the government let it happen yet had nil input to the planning.
See his Wiki page: https://en.wikipedia.org/wiki/Martin_A._Armstrong - went to prison for 11 years for fraud. I've followed him since his release and some of his predictions are uncannily accurate, although he was wrong about the currency crisis of 2015-2018. Also he is adamant that the gold market is not manipulated, which is way off base.
