I think that is surely the case. Firstly, I seriously highly doubt taking Ukraine in 3 days is objective in reality. It might be possible in some ideal conditions which is quite rare. Not to mention Ukraine is the biggest country in Europe and attacking big cities with so many streets is quite dragging, especially if military is on their foot most of the time. Was it months that Germans thought it would take them to conquer west in WWII? However, it took them years. Secondly, since Russia took a huge blow, I think they are taking their turn and kicking Europe (US included) in the nuts, being in power to create possibly biggest economic crisis (or at least bigger than 2008 one).
