Yeah and Russia protested strongly every time. But Ukraine was their red line. Just because you didn't read it in western media doesn't mean it didn't happen.
I don't condone the invasion but it was predictable and a colossal "failure" of diplomacy if you look at it charitably. At worst it was a long term plan to force Russia into a conflict with the aid of western media to obscure the reason why this war was happening. Russia is acting just like the US would.
