Why Meles of Ethiopia is "angered" about the agreement between Somalia,Kenya and Uganda?

The Ethiopian government of Mr. Meles allied with the Somali warlords-drug barons,All-Ittixad business cartels is planning as a "counter-action" to the recent trilateral agreement between the Somali Republic and Kenya ,Uganda to fight together the terror group Al-Shabaa a " new invasion" of Somalia..The Policy of the Ethiopians has always been a hegemonic approach to Somalia issues and to sub-divide it in clan-enclaves state regions-beak-away Republics. And from 2008 they started to introduce in the region politics and Somalia their big brother/ally mainly China and Iran. With the influence of China and Iran they were trying to have also a hegemonic approach toward the whole region of the Horn. With the total control of the resources of the Somali republic as Oil &Gas and Uranium which Iran is after and Somalia got in Abundance. The recent developments has angered Ethiopia in a big way because it "cancels" all its" Plans" .Therefore the only way for the Ethiopians is to anger everybody in the region by proposing the sub-division of Somalia as" area " of Invasion and "control". Also they know the Somali/people citizen will be angered by this move and will see in the same eyes Amisom and the Ethiopians which are not liked by the Somalis.I hope the U.N and Arab league, and the International community will tell the Ethiopians that Somalia is a Sovereign country and can decide who will be their ally or friend.Wait and see.
