America is behaving like every other country with power ever has, with mostly subtle differences. Some of these differences are comparatively better, some are comparatively worse.
It's not an issue of heritage or culture, it's an issue of being human animals. Speaking of things in terms of country ('America does this,' 'America did that') is an oversimplification that ultimately misses the mark.
Humans will act how they will act. Putting them into different contexts from one another will make them react somewhat differently, but at all times humans react how humans will react. Trying to paint fundamental differences is beyond illogical, it's uninformed.
