Roger’s article (https://rogerpartridge.substack.com/p/the-hidden-architecture-of-government) points out the danger of separating responsibility from consequence.  An interesting echo shows up in this article (https://www.programmablemutter.com/p/europe-has-more-bargaining-strength) on the power of the EU in confronting Trumps threats:

“The implication, then, is that the European Union might be much more credible with the Bessents of the world if they could more readily bind themselves to take painful or difficult steps to counter aggression. However, the European Union’s member states often look at the problem differently. They are worried about delegating security power to the European Commission, for fear it will do something that hurts their economic interests or other national interests. The Schelling argument is that this increases their flexibility, but weakens their ability to demonstrate resolve against outside threats.”

That is, the responsibility for security lies with the collective, but the consequences fall on individual states. Therefore, they are understandably reluctant to invest the collective with the requisite control.
