Military Times reports that “the military’s top officer said Monday that any deal for military cooperation with Russia in the fight against extremists in Syria will have to protect the ‘operational security’ of the ongoing U.S. mission.”  

“’We’re not entering into a transaction that is based on trust,’ Marine Gen. Joseph Dunford said at a press briefing at the Pentagon.”  

“’There will be specific procedures and processes in any transaction that we might have with the Russians that would account for protecting our operational security,’ said Dunford, the chairman of the Joint Chiefs of Staff.”
