A paper of mine has been recently accepted at International Affairs and will be published in early 2020. You can have a look at the pre-print version of the piece here; and I can send you the final version upon request. The paper for the first time systematically describes the various dimensions of the current crisis of world order and lays out a comprehensive research agenda, including several empirical entry points. As always: Please let me know what you think on Twitter or per Email!
