dude forget about Israel can Egypt handle Ethiopia thats the question? which is fairly no.One important aspect we need to see this from is that Israel is pushign the whole thing. They are currently paying alot of money to make saltwater to drink water. If they push Egypt from the lion share, they can make deals with Ethiopia. A funny little thing is that in the Torah it is written that Jerusalem is entitled to the nile water and will get acces to it through all times Heres some articles that discuss Israels involvment:

South Sudan will be a formidable foe to North Sudan.
Eritrea will not go against Ethiopia on Egypt and the other fufu countries will side with Ethiopia so who is on the side of Egypt.
I would have supported Egypt but they do no deserve my support they have been cheerleading for the destruction of the Arab states I guess its time Egypt riped what it sowed.
