France, UK, Germany Warn Sanctions if Iran Nuclear Talks Stall

France, the UK, and Germany have jointly warned Iran that they are prepared to reinstate UN sanctions through the snapback mechanism if Tehran does not resume nuclear negotiations or seize an extension opportunity by the end of August 2025. The snapback mechanism, part of the 2015 Joint Comprehensive Plan of Action (JCPOA), allows reimposition of UN sanctions lifted under the deal if Iran significantly violates its terms. The three countries communicated this position in a letter to UN Secretary-General António Guterres and the Security Council, emphasizing their commitment to prevent Iran from developing nuclear weapons. This diplomatic move follows heightened regional tensions, including recent strikes by the US and Israel on Iranian nuclear sites. Iran has expressed willingness for indirect talks with the US, but has suspended cooperation with the International Atomic Energy Agency, complicating the situation. The EU also signaled intentions to reinstate sanctions starting August 29 if progress on Iran's nuclear limitations is insufficient, highlighting the urgent timeline for diplomatic resolution.
