Do You Think Russia's Drone Attack Is a Provocation?

Three US officials tell NBC news that the aggressive action taken by Moscow to bring down a US drone over the Black Sea was approved by quote, the highest levels of the Kremlin. The Americans seem fairly confident that there is nothing on that drone that would give Russia very much information but even more confident that it'll be difficult for them to find it. It would be extremely hard for Russia to recuperate anything of value.
