Two years after the initial meeting, and after going through the UN and unsuccessful peace meeting with Emperor Haile Selassie, Yusuf Dheere was given the go ahead he wanted and was told to get control of at least 60% of the Ogaden region before the Somali army would involve itself in the fighting. The WSLF found its opportunity when the Derg overthrew Haile Selassie in 1974, and switched from American support to the Soviet Union. Two years later, when the WSLF had control of most of the Ogaden, the first time since the Second World War that all Somalia was united with the exception of the NFD region in Kenya.
