I believe the question has merit and I cannot really understand it myself. Obviously an invasion like Crimea or not the rest of Ukraine is a hostile act and specifically directed against "western influence". That said, the relationship with Russia was far better 15 years ago, there was an idea of Russia joining NATO even. I believe the following generation of politicians and diplomats were just incompetent in building a relationship with Russia and the same is true the other way around. There might even be interests in stoking the fire of such a conflict and perhaps the revolution in Ukraine was supported by outside forces. Or maybe Russia just suspects as much. Contrary to popular belief states aren't all-knowing. To be honest I wouldn't have expected Russia to invade further but it shows how much the relationship has degraded in the last decade.
