If you are asking why, you are not acquainted well enough with the russian mentality with (dis)respect to the west. Unless somebody rubs the scale of atrocity their ancestors commited into the following generations, they will feel like they got away with it, and perceive the west as soft and weak. Much in the same vein as Russia brazenly buying weapon tech and luxury items and electronics from the west, its rich and powerful spending holidays in and sending their kids to study in EU and US. All the while being a part of the global autocracy club and annexing its neighbors. Oh, and MH17 as a bonus, if you need a reminder.
