Diplomatic elder statesmen Henry Kissinger and Zbigniew Brzezinski told Fareed Zakaria on Sunday that Russia's prime motivation in its Syria diplomacy was stability. Speaking on "Fareed Zakaria GPS" on CNN, both said the superpower deal on Syria was designed to allow President Vladimir Putin to combat the tide of radical Islamic power in the region and also within his nation's borders - but that the U.S.-Russia deal on Syria also managed to extricate the United States from a difficult situation.
