A source who was briefed by U.S. intelligence analysts told me that they saw the attack as a rogue Ukrainian operation involving a hard-line oligarch with the possible motive of shooting down Russian President Vladimir Putin's official plane returning from South America that day, with similar markings as MH-17. But I have been unable to determine if that assessment represented a dissident or consensus view inside the U.S. intelligence community.
For its part, the Russian government has denied supplying the eastern Ukrainian rebels with a Buk system although the rebels did possess shorter-range, shoulder-fired MANPADs.
