As a result, the EU's high representative for foreign affairs and security policy sprang into action. In an op-ed in the Financial Times, Josep Borrell announced he'd submitted a new plan that couldn't include a better compromise. Can an accord be resurrected, or has Iran's nuclear program already come too far?
