The Bush Administration recently encouraged Ethiopia to invade Somalia, which had, after a number of years of quasi-anarchy, come under the rule of Islamic clerics. Who knows, it might work! An alliance with Ethiopia from the mid-1970s onward sure did the Soviet Union a load of good!
The funny thing is that forging an alliance with Abyssinia to catch the Musselmen in a pincer movement has been the most legendary of all strategic brainstorms. The Crusaders had heard that their was a Christian king named Prester John somewhere on the other side of the Islamic world, and their grand strategy was to get him to open a second front in the war with Islam. Eventually, they narrowed Prester John's home down to the Christian kingdom in the Ethiopian highlands, and over several centuries diplomatic missions were exchanged. Thirty Ethiopians visited Pope Clement V at Avignon around 1306. In 1520, Father Francisco Alvares was part of a 13 man delegation from the King of Portugal to Prester John, King of Ethiopia. Alvares published a detailed account of his travels in 1540. He returned from Ethiopia with a letter from the king of Ethiopia to the king of Portugal expressing the hope that "we might tear out and cast forth the evil Moors, Jews, and heathens from [our] countries."
