Holding a gun to someone's head and telling them that you won't shot them if they sign an agreement is not a contract.
Don't believe anything the US government says until they put something on the table for negotiation. How about ceasing to finance, train, supply and support the mercenary terrorists who used the chemical weapons.
Better yet; How about Syria giving up all of their weapons and the United States doing the same. At least when we get attacked then in this country we would know it wasn't our government doing it.
