This supported the possibility of war as appeasement allowed Hitler to challenge the Versailles Agreement with bold initiatives: withdrawing from the League of Nations (1933), canceling war debt payments (1933), starting a public rearmament program (1935) and move troops to the demilitarized German Rhineland (1936). By 1931 the vengeful mood of Britain in 1919 had transformed into one of guilt over the excesses committed to punish Germany. This feeling, combined with disgust and fear of a repeat of the "Butcher's Bill" of World War I, pushed British politicians to make mistakes. belief that “righting” the wrongs of Versailles would improve the situation and restore calm. However, when Hitler reoccupied the Rhineland despite the Treaties of Versailles and Locarno (1925). The Germans still could not resist any British and French military response, but Britain did nothing and France, which mobilized 150,000 soldiers behind the Maginot Line, would not have done anything else without British support. Hitler later confessed that if the French army had advanced into the Rhineland in response to his actions, the Germans would have had to retreat as they were unable to mount an actual action.
