Somalia

Back in December the wingnut party line was that Ethiopia would be untroubled ("There may be lessons for the United States in Ethiopia’s success") in its conquest of Somalia thanks to their affinity for brutal tactics ("Ethiopia has less concern than the U.S. about civilian casualties") and the absence of a troublesome press corps ("The Ethiopian government is generally less sensitive to media criticism than the U.S. government—and is likely to encounter far less criticism in the first place, since the press traditionally gives short shrift to coverage of Africa") thus guaranteeing success. It turns out, though, that you can have an insurgency anyway just about any time your country invades another one and tries to use its military to prop up a friendly regime on the conquered country's soil.
