Robert H. Jackson, “The Challenge of International Lawlessness,” American Bar Association Journal, Vol. 27, 1941, pp. 690-693. https://www.jstor.org/stable/25713307
Writing in 1941 as World War II shattered European order, Supreme Court Justice Robert H. Jackson confronts American disillusionment with international law. He rejects both idealistic faith in global organizations and isolationist trust in distance, arguing instead for clear-eyed pragmatism about law’s gradual development.
Jackson’s central claim challenges the surface narrative of total collapse: international law continues functioning beneath wartime chaos. Even dictators fear the stigma of illegality, he argues, demonstrated by their defensive denials rather than proud violations. He catalogs ongoing compliance with prisoners-of-war rules, diplomatic immunities, extradition treaties, and Geneva conventions as evidence of law’s persistence.
The League of Nations, despite failures, produced lasting achievements: treaty publicity, mediation techniques, and crucially, the legal delegitimation of aggressive war. Both the League Covenant and Kellogg-Briand Pact transformed war from a sovereign right into illegal conduct, reshaping neutrality’s meaning and making collective security conceptually possible.
Jackson identifies structural flaws that doomed peace: the League’s status quo bias and unanimity requirement created rigidity that stored grievances until violence became the only outlet. Future systems must permit peaceful change through flexibility rather than freezing power arrangements.
His enforcement argument borrows from Holmes: legal systems must deter the “bad man” who calculates only consequences. Civilization failed because it never convinced aggressors that keeping peace was advisable. Hitler’s incremental testing revealed that peace was lost not for want of great effort but for want of small, timely intervention.
Jackson frames America’s choice starkly: support law-based order or accept perpetual militarization that corrodes domestic liberty while failing to secure peace. International law becomes the cheaper, freer alternative to endless armament races.
