Hi John!
As a somali born in Ethiopia, i think i have some background of the issue you rised.
There has been a war and conflict between those two countries, it all started some time in the beginning of 15 cebtury when Itiopa tried to concur the Somali coast of Zayla and parts of Djabouti. Then Ahmed gurey repelled and defeated and took almost all Ethiopian teritory until he was killed. Since then there has been war going on and most of the time the reason is Ithiopian agression. The Itiopians lived in the highland and somalis the lowland, Ithiopia always wanted to swallow somali people, the somalis couldn't defend theselves. if i give you an example the area i came is known to Ogaden, Ethiopia cuptured the last 200 years still its population consist 100% somalis, they don't want Ethiopia but they are forced to accept. Now Ethiopia wants to rule the whole somalia and to have som kind of coast to breathe after it lost Eriteria. ( Ethiopia is the only black Colony on earth. We will se how it grows.
Thanks
