In May 1923, during a visit to Rome, the British Foreign Secretary, Lord Curzon, told Mussolini that Britain would cede Jubaland and Jarabub to Italy as part of a general settlement of all of Italy's claims, saying that Italians had to settle their disputes with both Yugoslavia and Greece as part of the price of Jubaland and Jarabub. Under the terms of the Treaty of London of 1915, under which Italy entered World War I, Britain had promised to cede Jubaland and Jarabub to Italy, and as Mussolini had founded the Fascist Party in 1919 in part to protest the "mutilated victory" of 1918 as Italy did not obtain all of the territory promised by the Treaty of London, Jubaland and Jarabub had over-sized symbolic importance in Italy far out of proportion to the actual value of these territories. To obtain Jubaland and Jarabub would mean that Italy would have to settle the Fiume dispute with Yugoslavia and the Dodecanese islands dispute with Greece, neither of which Mussolini wanted to compromise on. Through the Milner-Scialoja agreement of 1920 had committed Britain to cede Jubaland and Jarabub to Italy, the British had subsequently tied that to the Italians settling the Dodecanese islands dispute first. Under the Treaty of Lausanne in July 1923, all of the Allied powers abandoned their claims to Turkey, which badly damaged Mussolini's prestige as he promised as an opposition leader to obtain all of the territories the Italians had fought for in World War I including a large chunk of Anatolia. Having denounced his predecessors as weak leaders who had brought about the "mutilated victory" of 1918 and promised that he was a "strong leader" who would undo the "mutilated victory", Mussolini by the summer of 1923 was to face the reality that Italy was simply too weak to achieve all of his promises.
