In its editorial Wednesday, January 2, The Washington Post notes that the Obama administration and its diplomatic partners are expecting the renewal of negotiations with Iran over its nuclear program, after a six-month hiatus, but there is scant indication that a breakthrough is in store. The international coalition, composed of the five permanent members of the U.N. Security Council and Germany, intends to offer a slightly modified version of the deal Tehran rejected last June, with the faint hope that the pain of economic sanctions might have caused Supreme Leader Ali Khamenei to soften. If negotiations remain stalled, President Obama should consider making Iran a comprehensive offer that would permanently restrict its uranium enrichment and provide for intensive international monitoring in exchange for the lifting of sanctions. That would have the advantage of confronting the regime with a stark choice — and making clear whether a diplomatic solution exists.
