It seems to me that the Russian attack was more effective than the V1/V2 attacks, in that they managed to take out utilities and communications infrastructure.
Describing Russia’s response as Putin’s “temper tantrum” suggests that he is acting in a childish way and should be treated as if he is a child. That seems unwise because it might lead one to underestimate him. Putin may be many things, but he’s not a child.
“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
