We do talk in broad brush strokes about how overarching cultural norms impact the way countries act in a way that does seem to marry up with reality. The way the US acts does marry up with a commitment to a broadly liberal international order, underpinned by the principles of the Constitution. The UK acts in a way that is informed by its history and a respect for the rule of law. China and Russia, on the other hand, act in a way that respects individual sovereignty and the 'international order' much less.
The English school has much to say, even if you acknowledge that it may not pick up finer distinctions, and is still tied to a Westphalian view of the world (both valid criticisms)
