U.S. Secretary of State John Kerry is on a roll. Against the odds, Israeli-Palestinian negotiations are alive; the U.S.-Russia agreement for removing Syria's chemical weapons is working; and the U.S.-Afghan security pact is almost final.

In trying to convene a United Nations-sponsored meeting to end Syria's civil war, however, Kerry may be overreaching.

Last week, along with the "London 11" — which represents the core group of nations belonging to the Friends of the Syrian People — Kerry seemed determined to push for a round of meetings in Geneva, perhaps as early as next month.
