The silly thing is, while Russia was SSSR, it was King Kong to USA's Godzilla. She kept Godzilla occupied & focused. With the great nemesis gone, Godzilla has to find new outlets for all the pent-up rage & aggression.
So careful how you talk at Godzilla
The USSR provided a boogieman that leaders need to cultivate fear among the population, and, relatedly, served as the pressure to keep the military industrial complex fat and happy. When in collapsed we simply needed a replacement or series of them in order to perpetuate the structures that had evolved under the cold war scenario. I don't think that very many leaders in very many countries are driven by 'rage and aggression'...they would not have the skills to attain a high position. Nor do normal people fall into that orbital state by nature. The job of leadership is to provoke and direct 'rage and aggression' among the citizenry in order to achieve more useful objectives.
