The JCPOA got Iran to give up its Arak reactor, which if you are familiar with the plutonium pathway to nuclear weapons you would realize was the REAL nuclear weapons threat all along. Not Natanz or Fordow! Arak reactor could help build 10+ nukes a year via plutonium reprocessing. JCPOA was a trick to get Iran to give up its prized card in exchange for being able to sell oil more like it could from 1980-2007! Iran gave up SOMETHING to get basically what it already had before Obama era sanctions. No embargo lifting. No humanitarian sanctions lifting. No missile sanctions lifting.
