It is not human nature in the sense that humans will always do it when the opportunity presents itself.
What would be the best historical example that you can think of? To be specific, what is a historical example of when a country would have benefited from expanding an empire, had the resources and ability to do so, and chose not to for an extended period of time?
That would be a strange form of communism.
Human greed is a base desire that has been a constant throughout our entire history. At some point, you’re arguing for a fantasy. Either Communism is a realistic political system that can be implemented with humans as we are, including all of our base animal impulses, or it’s a fantasy that requires humans to achieve a higher level of consciousness first or something.
The threat of nukes is real. I wouldn’t expect any major wars between nuclear states right away, but there would be a lot of consolidation of smaller countries without nukes into larger countries with nukes. In this scenario if you’re Japan, you will have the option of getting nukes ASAP or deciding if you want to learn Russian or Chinese.
I’m not claiming that only xenophobia leads to military conflicts. It is often used to whip up support for conflicts that people in power want, though.
Soft power is preferable, yeah. The real measure is when someone has something you want and they say “no”.
Definitely agree that they’re all fucked up. It remains to be seen how much it helps vs hurts though. Like the saying “The market can stay irrational longer than you can stay solvent”, sometimes the fact that the metrics are all made up can be useful. I say that as someone that doesn’t like how little they resemble the real world.
