When Rules Break Down

On January 11, 2024, South Africa accused Israel of genocide before the International Court of Justice. Russia ignored the Court's order to halt its invasion of Ukraine. ICC warrants for Israeli and Hamas leaders drew sanctions threats from Washington. The Security Council is paralyzed; treaties are abandoned, rulings defied, the rules-based order crumbling. International law has no police force. That is not a weakness but the condition it was built for: from Westphalia to San Francisco, no state strong enough to build enforcement machinery has been willing to build one binding itself. What does such a system do? It works through three mechanisms that operate without compulsion: the cost a violation imposes on the next transaction, the vocabulary by which even the strongest states justify themselves, and the record that accumulates and waits. Power without legitimacy must be reapplied in every instance; legitimacy secures compliance when no one is watching. The diagnosis of collapse is misleading. International law has survived existential crises before, such as the League's failure and the post-Cold War upheaval, and has emerged transformed. The question is not whether it survives but what form it takes in a multipolar world: thinner principles commanding genuine consensus, a patchwork of regional geo-legal orders, or a system that constrains raw power.
