While the Inquiry acknowledged that the Brenner Pass (as promised to Italy in the 1915 Treaty of London) would give Italy the best strategic frontier, it instead recommended a line somewhat to the south of it in order to reduce the number of ethnic Germans who will be put inside of Italy (while still giving Italy a more defensible border in the north than it had before World War I). In addition, it was suggested that Italy be allowed to annex Istria (with its large number of ethnic Italians) but not Italian-majority Fiume due to its importance to Yugoslavia. In addition, it was advised that Italy should end its occupation of Rhodes and the Dodecanese Islands and give these islands to Greece in accordance with the wishes of these islands' inhabitants (something that was ultimately done, but only in 1947 after the end of World War II). Also, the Inquiry recommended that Italian Libya be given a hinterland adequate for access to the Sudan and its trade.
