What is clear for me, that Russia took Crimea or annexed without any murders.
They executed an old plan/dream, that they had no right to. Ukraine gave away their nuclear weapons so that RF would respects its territory. Of course, RF has had its fat fingers in Ukrainian politics since its inception. Even the RF developed (Excellent) flight sim Su-27 from 1996 had crimea as the only map and scenario, with the main thing being Ukraine vs RF.
Also Russia helped Donbass in their rebellion with troops and weapons.
No, RF created the rebellion, tried to make it look like a natural Maidan. I remember the videos of pure white sandbags blocking streets. It was not a people's revolt, but planned, started, commanded from RF, again with semi-military means. A more advanced version of crimea.
Ukranian army shelled Donetsk and Luhansk
Afair the first reports of artillery being used was RF shelling of Ukrainian troops from across the border. IMO Ukraine commanders had no option but to set hard against hard. RF just responded by escalating the brutality at will. They had thousands of soldiers ready across the border, shuffling them in and out as they wanted.
Sometimes this shellings were at positions, where no separatists were noticed. It was schools, hospitals.
I'm sure shit happens in war, both ways. Sometimes Ukrainian separatists "finds" BUK's and shoot down civilian airplanes.
And I watched opinion of Donbass people and people on the west. Nobody wants this war. And people in Donbass hate Poroshenko.
Considering you are in deep shit if you air your true opinion about separatists, that such opinion would never be broadcast in RF media, that most Ukr sympathizers have run away long time ago, considering that RF propaganda has been bombarding Ukr with bullshit about baby crucifixion style lies since the start of the conflict... well no shit, im sure they hate Poroshenko. The rest of Ukraine now hates Putin though.
Go see the vice documentaries from maidan, crimea and on.
The only thing is that nobody wants this war, except Putin of course. The war is absurd, and its mostly about russian pride.
