The memo, according to the Times, calls for "a judicious use of stand-off and air weapons" — in other words cruise missiles, drones and perhaps direct US air strikes.Mr Kirby said US secretary of state John Kerry "values and respects" the device, but would not be drawn on whether he believes this China oil Seal specific complaint has merit.Meanwhile, Russia on Friday condemned a US diplomatic cable calling for military strikes against the Syrian government, as Washington again accused Moscow of bombing US-backed rebels in the war-torn country.A group of US diplomats have used a state department channel for dissident views to criticise President Barack Obama’s Syria policy, a spokesperson confirmed Thursday. With only seven months left in office and a clear aversion to getting bogged down in West Asia conflicts, Mr Obama has shown little appetite for such action.".US forces are engaged in Syria but are assisting local militias to fight the Islamic State jihadist group, not confronting Assad’s Russian and Iranian-backed forces.The official would not discuss the contents of the cable, but the New York Times and Wall Street Journal said the dissenters call for US strikes against the Syrian regime.Russian officials criticised the so-called "dissent channel" cable signed by a group of US diplomats urging strikes against Bashar al-Assad’s regime, which it accuses of persistently violating a shaky ceasefire aimed at bringing an end to the conflict.

"Of course this is at odds with (UN) resolutions," Mikhail Bogdanov, Russia’s deputy foreign minister, said of the calls in comments to Interfax news agency. "We need to negotiate and reach a political resolution on the basis of international law, which was agreed upon at the UN Security Council," he said."We are reviewing the cable now, which came up very recently," he added.
