Four weeks after agreeing in principle to nuclear talks, Iran has gone silent about its plans for the negotiations, baffling U.S. and European diplomats while also signaling internal discord over what analysts see as the best chance in years for a nuclear bargain with the West, The Washington Post reported Wednesday, January 16. Prospects for the talks — which U.S. officials last month described as imminent — have grown more uncertain after Iran declined to respond to at least two proposals for meeting dates. Iranian and European Union officials discussed logistical issues by phone on Monday amid hopes that a meeting could still occur before the end of the month. But with progress at a crawl, officials and analysts on both sides expressed concern that the chances for a deal were being undermined by political divisions. Hard-liners in Iran have spoken publicly against making any nuclear concessions.
