I heard the balance of power argument before and, well, you were already granted this wish ( and I would argue that you had it granted twice ). Both China and Russia are very capable adversaries at this time and US is slipping from its top dog position. It is genuinely sad to watch.
Russia is a terrible threat to the US. How much/many of their disinformation and memes (in the traditional sense) are correlated with disrupted political discourse, extremism, and disunity in the US? They don't sponsor squads of disinfo/misinfo actors just for giggles. It has a profound destabilizing bang for their buck.
