In the meantime it has become clear, both about my own feelings and those of the world opinion, that part of the outrage here is that while there are "areas of unstability" in the world, and people generally accept that this is how we see the world, Europe was supposed to be "done" in this regard after the fall of the Iron Curtain.
There was fallout in Yugoslavia, there were border disputes in the ex-Soviet Union countries. It was shocking enough when Russia took Crimea, but it still fell under extreme hustling and stretching limits. Russia had their naval base there, it was majority ethnically Russian, kind of a grey area in terms of valid cause, not legally but morally.
A full invasion of Ukraine is unlike what the US did to Serbia or anything post-Soviet Russia has done to its neighbors before. It's a new chapter in what people allow themselves to do in Europe after WW2. Russia hasn't gone after someone's capital since Budapest 1956.
