I am not sure if it can be marked just as a kind of “bad season”.
Russia assumed it would show up with a lot of tanks and soldiers and Ukraine would give up and let them walk in. America was the same, they assumed they would show up and Iran would also give up the next day.
In both cases its obvious both are not only arrogant and didnt study their opponent, but we can also see they are effectively a parade that shows and hopes the public and others believe far more about their capabilities. THey hope others scare themselves, because the reality is they are far less capable than what we thought before hand.
Before the Iran invasion i wondered for how long did the west know the USSR was not that strong because their reaction to the invasion was imho very limited. It seemed to me that JFK really reacted to the Russians during the missile crisis but in the modern equivalent with the Ukraine invasion, NATO itself did not do that much.
In both cases, RUssia and America tried to play poker... and lost.
