Oh shiiit, I have this video which touched very sensitive issues. Here are they:
1) First of all I even don't know Emperor Minilik signed any agreement with British on the Nile river. But this video showing us this document (16:32).
2) Amazing! Egypt was telling us how it stopped the construction of the biggest Ethiopian dam in 1976 by bombing the equipment which was destined to Ethiopia by sea. Just go to 23:10
3) This video telling us even if Egypt was directly involved in destroying Ethiopian's dream, they were involved in destabilizing the Ethiopian state by supporting TPLF and EPLF fighters (20:44).
4) Amazing! It was telling us also the secession of Eritrea was backed by Egypt. Just go to 20:51.
