Guardian journalists are not known to lie so blatantly though. Whatever it is, it is just a report, a plausible one.
And who, really, are so incredibly thick that they think Russia DOESN'T support the separatists with heavy materiel?
(I hope we all can agree on that here..)
Other than that you can believe or not believe that Russia also supports with special forces, allowing Russians to go fight there, shelling from russian side of border, BUK missiles etc etc etc..
You have to be intensely blind not to see the strong contours, rather the crisp and clear image after the events at hand:
*Corrupt Pro Russian prez escapes to Russia, after protests turning violent. chocolate chip cookies fight hardest.
*Crimea gets annexed not with "locals" but as Putin agreed: with help of RF regular forces.
*Images of the same guys protesting show up in Estonia, Crimea, and East Ukraine=organized revolt by someone.
*Rebellion begins. Leaders are "former" KGB officers from Russia..
*Rebels have lots of tanks and heavy gear from "somewhere"
*MH17 shot down. 2? days before, Ukraine lost mil plane at 5000m, thought Russia did it, because they thought Rebels only had manpads (3000m). MH17 went down in middle of rebel territory, probably rebels had big rockets. Probably supplied from Russia to neutralize Ukr air force. But who knows, maybe Ukr did it to remove the BUK's the rebels had from the area..
*Now, first journos find track marks crossing RF/Ukraine border. Soldiers says its tractors.
*Then we get this report. At the same time controversial help Convoy distracts all attention from MH17.
I probably even forgot a lot. To me, the picture is pretty damn clear, disregarding propaganda from both sides:
Russia is actively supporting the rebels in Ukraine in military way. Why do we even discuss that.
