I can assure you that war-torn Ethiopia has neither the power nor the capability to invade Eritrea or any other country in the region, so calm down and don't put your dirty finger on Djibouti.
And please get this through your oversized ugly head.
France didn't seize Djibouti from Menelik because it wasn't his property in the first place, Djibouti was never part of Ethiopia, Menelik baptised as Sahle Maryam was King of Shewa from 1866 to 1889 and Emperor of Ethiopia from 1889 to his death in 1913, at that time, Djibouti was already French colony of Somaliland, Menelik was illiterate primitive puppet warlord of the European colonialism, War-torn Ethiopia history is a pure fabrication and fiction.
France interest in Djibouti began the opening of the Suez Canal in 1869, between 1883–87, France signed various treaties with the then ruling Somalis, which allowed it to expand the protectorate to include the Gulf of Tadjoura and named the region la Côte française des Somalis (French Somaliland), a name which continued until 1967.
Leave Djibouti alone.
