They will kill you, and the Arabs who cannot even defend themselves surely won't defend you. You are forgetting it's not no petty Arab dispute. The masters of the Arabian peninsula, who are Persians and not Arabs, conquered Iraq, Iran, Lebanon, Egypt, Bahrain, Oman and soon Yemen. They've already began their mission in Nigeria, and have converted 10 million Bantus since 1980.
If you involve yourself in their business, then you will go down like Saudi Arabia will in due time. This is not even talking about Ethiopia, who you are dependent on for water, electricity, food, your culture and almost everything.
Dependent on Ethiopia for culture? What do u mean?
Also from what I know we don't get water nor electricity from Ethiopia.
