This just straight up doesn't make sense to me—states aren't monolithic entities or rational actors. I think it's easier to say that the modern state exists at the behest of capital, at least in the west.
when in the history of anything was that the case? democracies make terrible choices, with voters often voting against their interests all the time.
dictators make dumb-ass calls often, like Erdogan of Turkey making random (randumb) pronouncements about the currency and causing terrible inflation (or Saddam's "let just fight all our neighbors, Suharto's random evil, etc.).
It’s generally accepted in international relations that it’s always the case long term. States can make bad calls in the short term but you’ll often find they are rational decisions regardless of if they don’t turn out well. Erdogan has greatly expanded turkeys influence in the region and been relatively successful in playing the west and russia off each other for instance.
Saddam I’ll give you but that also led to his removal and it can be argued Iraq didn’t have many good options as historically it’s been controlled by one or more of the surrounding nations so it may just not working realistically due to geography and ethnic strife
> States can make bad calls in the short term but you’ll often find they are rational decisions regardless of if they don’t turn out well.
This line of reasoning only makes sense when compared with counterfactuals, which seems like a waste of everyone's time. It's easy enough to justify an arbitrary action as rational if you have no basis of comparison.
Anyway, "rational self-interest of the state" is not the same thing as "rational". There are other ends other than self-interest of the state—for instance, self-interest of the constituents of the state, or self-interest of humanity. All states put their own existence before the welfare of their people. A state is not a natural thing outside the vying of capital to institute economic stability for the ends of its own empowerment.
Your politics are bleeding through here and it’s clearly fogging your mind of reality. I made a statement considered factual by political science/international relations and you’re strawmanning about “neoliberalism” and bringing up climate change. Do better, be less emotional. If you can’t do that you have no business making statements about nations and their relations with one another which are rational.
