My 2 cents is Russia has been fighting a rear guard action against aggression for years. Considering the psychological impact of Germany moving so fast East in the Second World War and that geography makes Moscow vulnerable, it’s hard to perceive of other responses from them. The question I always have is if USA/Europe stop attacking people all over the world, would we have more peace or would those that we attack feel emboldened to project state violence? We cannot know the answer until western nations stop attacking other nations perpetually.
