I had the pleasure of encountering Nathan Sears on two separate occasions—in the first week of his PhD and on the final day of his life. The first time we met, Nathan's ideas about why Great Powers fail to effectively address existential risks were just starting to take shape. The second time we met, Nathan, now a newly minted PhD, presented his fully formed theory of macrosecuritisation failure at the International Studies Association conference in Montréal.
