This increasingly looks like a repeat of a Finnish war (1940), a colossal blunder when the Red Army couldn't push the Finns off their positions for almost two months, taking huge losses.
Russia has a 'tradition' of stating what seems a 'small victorious war', aiming to boost popularity and support for the government, and then blundering badly - Russian-Japanese war (1905), Russian-Finland war (1940), Afghanistan invasion (1980), two Chechnya wars (1994, 1999). So far, Ukraine 'special operation' seems to be a one more addition to this ignominious list.
