vocal Socialist League opposed the official policy, on the non-pacifist ground that the League of Nations was 'nothing but the tool of the satiated imperialist powers'." Lansbury was eventually persuaded to resign as Labour leader by the non-pacifist wing of the party and was replaced by Clement Attlee. As the threat from Nazi Germany increased in the 1930s, the Labour Party abandoned its pacifist position and supported rearmament, largely as the result of the efforts of Ernest Bevin and Hugh Dalton, who by 1937 had also persuaded the party to oppose Neville Chamberlain's policy of appeasement. The League of Nations attempted to play its role in ensuring world peace in the 1920s and 1930s. However, with the increasingly revisionist and aggressive behaviour of Nazi Germany, Fascist Italy and Imperial Japan, it ultimately failed to maintain such a world order. Economic sanctions were used against states that committed aggression, such as those against Italy when it invaded Abyssinia, but there was no will on the part of the principal League powers, Britain and France, to subordinate their interests to a multilateral process or to disarm at all themselves. Spain The Spanish Civil War proved a major test for international pacifism, and the work of pacifist organisations (such as War Resisters' International and the Fellowship of Reconciliation) and individuals (such as José Brocca and Amparo Poch) in that arena has until recently been ignored or forgotten by historians, overshadowed by the memory of the International Brigades and other militaristic interventions. Shortly after the war ended, Simone Weil, despite having volunteered for service on the republican side, went on to publish The Iliad or the Poem of Force, a work that has been described as a pacifist manifesto. In response to the threat of fascism, some pacifist thinkers, such as Richard B. Gregg, devised plans for a campaign of nonviolent resistance in the event of a fascist invasion or takeover. France As the prospect of a second major war began to seem increasingly inevitable, much of France adopted pacifist views, though some historians argue that France felt more war anxiety than a moral objection to a second war. Hitler's spreading influence and territory posed an enormous threat to French livelihood from their neighbors. The French countryside had been devastated during World War I and the entire nation was reluctant to subject its territory to the same treatment. Though all countries in the First
