After the break-up of the Soviet Union, for those people over there, one can imagine that that was a sensitive subject that still has repercussions today. In a way, it's understandable that Moscow might be aggravated over this though, of course, I consider the USSR and the subsequent leaders usually very harsh. I don't know if there is an exception to this.
Again, real history to it. At one point under Yeltin, didn't they storm the Parliament and the Military move in? Or they bombed the place with airstrikes? There's a lot of history.
