Intrigued by signals of an invigorated papal diplomacy, U.S. Secretary of State John Kerry enlisted a new ally Tuesday in his push for Mideast peace in what he described as a "common enterprise" between America and the Holy See. In a brief visit to the Vatican, Kerry did not meet with Pope Francis, and said he had not expected to. However, he described a broad conversation with the pope's chief diplomat, Archbishop Pietro Parolin, that touched on everything ranging from violence in Syria and Africa to ending a generations-long feud between Israel and Palestine and addressing climate change and poverty.
