(CNN) -- The United States isn't leaving anything to chance. While it pursues a diplomatic solution to the Syria crisis by sending Secretary of State John Kerry to meet with his Russian counterpart in Geneva, Switzerland, on Thursday, it has also started arming the rebels. Two rebel groups, though, say the arms have yet to reach them. Meanwhile, a Vladimir Putin-penned editorial in The New York Times has at least one White House official saying it's an indication the Russian president is "now fully invested in Syria's chemical disarmament." And a U.N. report says that both sides -- the regime and the rebels -- have committed war crimes in Syria's bloody 2-year-old civil war.
