They did agree first but they changed their minds soon, as Soviet started to influence the world and the cold war started. The Italian got back their colonial with a condition and that saved Somalia. Because soon after that the British gave Hawd to Ethiopia and later NFD to Kenya.

SYL or the leegada was the best organization Somalis ever had. Without money, they manage to unite Somali people around the horn. They opened offices everywhere the Somali people reside. From Jigjiga, Jabuuti, Hargeysa to Gaarisa and dealing with three EU colonial and Haila salse by the time. They were right not trusted the British, the Kurd did and paid the price.
