The Bevin-Sforza Plan was a 1949 attempt by Italy to recover some of the lost colonies, through agreement with Britain backed by French support.
It would partition Italian colonies as such:
- 10-year UN Trusteeship Mandates on Tripolitania (Italy), Fezzan (France) and Cyrenaica (UK), followed by full unitary independence
- partition of Eritrea between UK-Sudan and Ethiopia
- 10-year Italian Trusteeship Mandate over Somaliland (as eventually happened).
The proposal wasn't ratifed by the General Assembly by a single vote's margin; the reasons, as noted
here, were lukewarm US support and conflicting interests. However, it shouldn't be too hard to either convince Sweden to help out or to have the Haitian diplomat not defy his government's wishes and vote for (though the man was a staunch anti-colonialist, so you probably need to butterfly his appointment).
Also considering how the US saw that proposal as a turning point in having to assert themselves more on those delicate anti-colonial issues, and the raging rebellions against such a plan in Libya itself, what do you think would be the consequences? Would this help keep the Libyan macro-regions separate? Would Italy try to hold onto Tripoli?
