(CNN) -- Diplomacy is never easy. Top diplomats of Iran, the United States and other permanent members of the U.N. Security Council, plus Germany, spent three days debating a first, interim deal on Iran's nuclear program. And an agreement was found: After 34 years of estrangement, Iran and the U.S. were finally on the same page. Still, the deal fell through. French Foreign Minister Laurent Fabius showed up in Geneva, Switzerland, a day into the talks and adopted a hawkish line that guaranteed the failure of the discussions. And much to the dismay of the other diplomats involved, Fabius broke protocol and announced both details of the talks and the failure to reach a deal before U.S. Secretary of State John Kerry had a chance to address the media. Fabius, echoing the objections of hard-line Israeli Prime Minister Benjamin Netanyahu, argued that Iran would get too much in the proposed deal. But in reality Iran was only offered modest sanctions relief in return for some significant suspension of aspects of its nuclear program.
