2015 was the year of a landmark deal, the JCPOA or Joint Comprehensive Plan of Action. But before it could take off, Action had its wings clipped.
In 2018, the former US government pulled out of the deal. Iran fulfilled all its commitments without other parties complying with their undertaking. As a result, Iran reduced its commitments as far as stopping IAEA inspectors visits to its nuclear installations.
But this year, has with modest moves, also accomplished something as significant: steps taken to save the JCPOA from demolition. That makes for a good prospect, but Iran is not banking on it.
The JCPOA or nuclear deal was between Iran and P5+1 countries. Those are the US, UK, France, Russia, China and Germany. 22nd February saw a logical turn of events. Iran was to end free visits by nuclear inspectors that day, if the US did not lift all sanctions as commanded by the JCPOA.
Sure enough, the US did not lift sanctions. But contrary to expectation, Iran struck a deal directly with the UNs nuclear watchdog. This would buy three more months, to give diplomacy another chance to make the deal work.
Irans nuclear activities would be recorded, but by Iran itself.
