What is your idea that they “can’t get away with dropping bombs” based on? They absolutely could, and they still don’t do it. What it’s based on is that you assume they would if they could, that’s projection, because clearly you like the idea of bombing people for profit.
To be blunt, have you? If you had you would know that even among empires not every one behaved with the same level of bloodthirstiness every time. The leap from “people have been violent forever” to “therefore they must be the maximum amount of violent at all opportunities” is totally unsubstantiated.
Sure, what they can get away with to achieve their goals is one factor in how countries behave. But it is totally absurd to suggest that a country’s culture would have no impact on the approach they take to foreign affairs. It has dramatic impacts on all their other laws and ways of doing things, by what possible crazy coincidence would foreign policy always be totally identical regardless of culture?
So yeah, things would be different. Way back in this discussion you snarkily characterised a straw man arguing that things would be perfect and people singing kumbaya, but nobody (here arguing against you in this thread) thinks that. This meme is about dropping bombs. We have substantial real world evidence that China does not prefer to take that approach. The USA absolutely does prefer to take that approach, even when other options would be more successful.
