While Enrique Mora, the EU official chairing the talks, said he feels positive about what he heard in the talks on Monday, Dr Neil Quilliam from Chatham House seems sceptical. He told Express.co. The EU has very little leverage in its attempt to revive the deal in 2015, where Iran limited its uranium enrichment programme in return for a lifting of crippling economic sanctions from the US, EU and UN. When the deal, known as the Joint Comprehensive Plan of Action, JPCOA was abandoned in 2018 after Donald Trump pulled out, fears that Iran has restarted its nuclear weapons programme and are even one to three months away from having nuclear weapons has left the EU scrambling to revive it. Dr Quilliam spoke to Express.co. I am not particularly optimistic or hopeful that there will be any major or significant breakthroughs. This is the seventh round of talks and they have been on hold since June. I am not sure if they can make matters worse or better, this is more about the US and Iran. They have very little leverage over this, to be honest. They are trying to be a bridge between the US and Iran, and that hasn't had much success clearly, so I don't see them as having a major role to play. While the EU was expected to struggle to make a dent in negotiations, Dr Quilliam warned that Iran is close to being able to enrich uranium to weapons-grade. He told Express.co. Whether they are one month off or three months off, it seems like that is the direction they are going and most analysts say they are close to a breakout position. A military action or diplomatic pressure can stop a nation from reaching nuclear weapons capability when a military action is taken over by diplomatic pressure or diplomatic action. A former head of the Iranian Atomic Energy Organisation, Fereydoun Abbasi-Davani, admitted that Iran has a system with military capabilities in an interview with Iranian state media. Amos Yadlin, the former head of Israel's Military Intelligence, warned on Friday that Tehran will be just two months away from a nuclear bomb under a renewed nuclear deal.
