While Pax Americana does have some benefits (but not for everyone), taking examples from history is worse than useless when nuclear weapons have completely changed war. China might be eyeing Siberia for all its space and resources, but unlike in the modern era, the chance that they will declare war on Russia is basically nil. It even predates nukes when you look how WW1 and WW2 had only losers (nothwithstanding those that didn't let war touch their territory, like USA). But I guess that we were too "dumb" to figure that out before nukes. And still are, Russia is getting an example of it in Ukraine right now... speaking of, what "rules" ? Russia just went and completely ignored the Budapest memorandum (while Ukraine is regretting deeply they didn't keep at least some nukes).
