After Ukraine and Gaza, how should we think about the power of international law? Does it have any? This talk will examine the different ways in which international law as a professional language, a set of institutions and practices, frames and informs the life of international actors. International law is not only, or even predominantly something that those actors “use” to advance their interests (though it is that, too). Its principal power lies in the way it lays down the conditions in which some groups are qualified or disqualified as “actors” as well as canvasses the rules of diplomatic, commercial and belligerent behaviour they should follow to qualify as “lawful”. Owing to the open-endedness of those rules, international law has recently come to intervene powerfully in the daily practice of international political contestation. Instead of absent from the world of power, international has come to legalize the way we address it.
