Michael Ledeen plays Sherlock Holmes in his attempt to learn whatever happened to the Iran Deal. His visit to the John Batchelor Show on December 2 starts around the 10:25 mark on the podcast. He also wrote on the same topic for Forbes but his verbal explanation is more fun.
I never wrote about the Iran Deal because I considered the deal was actually hammered out between Washington and the EU governments that most wanted to do big business with Tehran. From that viewpoint Washington was just trying to establish how far Brussels, London, Paris and Berlin would be willing to take trade with nuclear-armed thugs.
