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

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.
