The JCPOA (Obama‘s deal) wasn’t perfect and didn’t stop a nuclear weapon or nuclear enrichment for Iran. At best it delayed it for a decade. It also didn’t do anything about Iran ballistic missile program. In fact the same year the JCPOA was signed, Iran built a big public clock counting down to Israel‘s destruction in Palestine square. It would reach zero the year the JCPOA ended. So much for their peaceful intentions. The JCPOA only kicked the can down the road with the hope of a more sane government in Iran later on.
