The entirety of Shabelle and Jubba belong to Somalis I won't share what is mine by right.Egypt only wants to use Somalia as a proxy in its conflict with Ethiopia. Egypt does not have our interests at heart, therefore we should remain neutral in that conflict.
We should negotiate with Ethiopia on how to share the Shebelle & Jubba rivers. However, if nothing comes to fruition then we can form a temporary alliance with the Egyptians to weaken the Ethiopians if they do not come to an agreement us on the Jubba & Shebelle rivers.
