William Drozdiak, The Brookings Institution (USA)
For anybody who spends time in Brussels, one of the more baffling mysteries in the self-styled “capital of Europe” is the lack of communication between the North Atlantic Treaty Organization and the European Union. Even though these vital Western institutions are located just a few miles from each other, there is a striking absence of policy coordination between them. This, at a time when the European continent is confronting multiple crises whose solutions will require ingenuity, innovative thinking, and smarter use of resources.
