So, these "rebels" are suddenly all under Putin's command after all? 
Nothing I haven't been telling you for along time. It is a Russian invasion of Ukraine, it has been from day 1.
Igor Girkin was the FSB (KGB) leader that organised the attacks and takeover of Donetsk and surrounding areas Ukrainian administration buildings to form the DNR and was their military commander has been very honest on this after he was deposed.
The hard lesson that Russia is learning from what has happened in East Ukraine is the limits of their deniable hybrid wars. This is they don't work when you have a disinterested / hostile Russian population you are there to 'defend'. This is good as it will help to stop this happening in the Baltic countries. The other lessons is that employing Russian unemployed alcoholic bums with a bit of past military service as mercenaries is that they are not very good, are pretty uncontrollable, and are a definite liability by the time they are pissed on Vodka from the late morning onwards. One of the Ukrainian Oligarchs who has been supplying humanitarian aid to the Donbas has contraband confiscated by the Ukrainian authorities, where it contained a large percentage of tobacco and vodka.

The Western MSM have been awful, it makes you realise how very poor they are, when you go to much more direct sources for news from both sides. The BBC is classed and joked about as a tragic laughing stock by those that know better. Like "How much they have earned off Putin to today for each use of the words 'rebels' and 'separatists'!" A big problem is that many Western correspondents covering Ukraine are based in Moscow and you don't get asked to leave Russia by broadly following the Putin propaganda line.
TBH covering what is happening in Ukraine through hundreds of direct sources has been a real eye opener for me on how very poor and manipulated the West's MSM are.
It has also exposed some sources for good like 'bellingcat' run by a Brit 'Elliot Higgins' where it is a forensic analysis website that is doing much good in gaining evidence on the shooting down of MH17 and also the use of chemical weapons by Assad in Syria which is still going on!
Another thing I have learnt is that the Kremlin always signal their intentions to test western reaction and if negative / push back against Russia they will reconsider, by they always get the green from Western indifference and slow reaction, which is why things are so very dangerous for Ukraine and Western Security right now.
