South Sudanese Foreign Minister Barnaba Marial Benjamin, right, welcomes US Secretary of State John Kerry upon his arrival at Juba International Airport, South Sudan, Friday May 2, 2014. Kerry, landing in the capital Juba on Friday, carried the threat of U.S. sanctions against prominent South Sudanese leaders if the rampant violence doesn’t stop. But more than anything, he sought to compel authorities on both sides of the fight to put aside personal and tribal animosities for the good of a nation that declared independence three years ago to escape decades of war.
