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. Though 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. There was a boundary dispute between Greece and Albania. The two nations took their dispute to the Conference of Ambassadors, which created a commission of British, French, and Italian officials to determine the boundary, which was authorized by the League of Nations to settle the dispute. The Italian General Enrico Tellini became the chairman of the commission. From the outset of the negotiations, the relations between Greece and the commission were bad. Eventually the Greek delegate openly accused Tellini of working in favour of Albania's claims. In July 1923, Mussolini ordered the Regia Marina's admirals to start preparing for Corfu's occupation, which he predicated would happen that summer in response to the "expected provocative acts" by Greece. The Italian Navy minister, Admiral Paolo Thaon di Revel, welcomed the plan to seize Corfu for budgetary reasons, believing a triumph by the Regia Marina would show the Italian people the navy's importance and thus lead to a bigger naval budget. At the same time, Mussolini did not inform the professional diplomats of the Palazzo Chigi about his plans to seize Corfu, expecting them to object, an expectation that was confirmed when Corfu was indeed bombarded. Tellini's murder On 27 August 1923, Tellini and two aides, plus an interpreter and a chauffeur, were ambushed and assassinated by unknown assailants at Kakavia's border crossing, near the town of Ioannina in Greek territory. The five victims were Tellini, Major Luigi Corti,
