"Covering eight treaties, with 118 national ratification processes, has been a big job. Closa deserves credit for carrying out this job. The amount of detail is impressive.

In the end, success requires successful framing – some would prefer to say leadership, a term Closa uses more sparingly than framing. Some rationalist scholars, including this reviewer, would prefer to talk about leadership as a decisive ingredient of success in overcoming ‘collective action’ problems, without ignoring social constructivist explanations."- Finn Laursen, European Political Science,
