This is misleading. The JCPOA was not '"designed to give Iran nuclear weapons." It had built-in sunset clauses (key restrictions on centrifuges, stockpiles & enrichment phasing out after 10-15 years).
Obama explicitly warned it wasn't a permanent fix but was the best deal the P5 1 (US, UK, France, China, Russia) Germany EU could get with Iran at the time. He said a follow-on deal would be needed to avoid zero constraints.
This short MOU gives upfront sanctions relief, asset unfreezes & reconstruction funds — all while leaving Iran's advanced nuclear program at "status quo" (???), with weaker verification than the JCPOA & no requirement to ship out enriched uranium (like the ~97% that left the country before JCPOA implementation) back in 2015.
Claiming this MOU is better is pure cope, and you know it. We deserve to know wtf is going on so how about being honest for once?
