Name one country with a large military force that done more good than bad with it? Seems to come with the territory that if you have a large military force, you somehow need to use it for something as otherwise it falls into disrepair, and that "something" tends to be trying to spread your culture one way or another.

Come to think of it, seems China is the only country so far (in modern times) that haven't abused their military to enforce their will on smaller countries, basically every other superpower been abusing their military to make the world worse.
