The always-interestings, but never-verifiable Wayne Madsen has posted the following:

Ukrainian government, Russia, and Donetsk People’s Republic all deny shooting down Malaysian Airlines flight 17 over eastern Ukraine. But there is no word from Kolomoisky’s Army led by Ukrainan-Israeli billionaire oligarch Ihor Kolomoisky. Kolomoisky has funded his own army in eastern Ukraine with massive weapons purchases and fascist mercenaries. The Buk missile system used to shoot down MH-17 is in Ukrainian stocks and has been sold by Kiev to Georgia. Media propaganda alert over charges that Ukraine does not possess Buk system. Donetsk Republic also says it has no missile system capable of hitting a plane at 33,000 feet. The truth: Kolomoisky, who takes his orders from Tel Aviv, pulled this attack off to divert attention from Israel’s Gaza genocide and try to put blame on Russia. Israel and its sayanim are masters of false flag attacks.

Prior to reading this, I had assumed the following ordering of likelihood of guilt:

Tied 1) and 2) and 3) Ukrainian government , separatists , US (covert op)

Distant 4) Russian government (essentially 0 probability)

Then again, what I know about the Ukraine would struggle to fill a thimble. I never even heard of Kolomoisky.

Well, make of this what you will.
