Malaysian Jet Down-Who Ordered the Trigger Pulled?

Was it:

An overeager, small-minded and shortsighted separatist commander?
A never to be discovered order that came from Putin to serve as a shot across the bow in response to yesterday’s increased U.S. sanctions, which the Europeans are paying no more than lip service to, which is the way Putin wants it to remain?
