The idea that Ukraine just randomly or maliciously suddenly started shelling the Donbas is so dishonest. It is just backwards and factually incorrect. This was a huge violent escalation by Russia. Russia armed, trained, and manned a separatist army in Eastern and Southern Ukraine to destabilize Ukraine when they couldn't get what they wanted via corrupt politics and intimidation. The separatists launched attacks all over and seized areas of Ukraine. Of course Ukraine tried to take back control of its own sovereign territory. A little bit more research while putting bias aside would help a lot.
