well, he's not completely incorrect -- the Italians DID get their a$$es handed to them in Adowa (they were, however, vastly outnumbered).
But why he refers to an Ethiopian battle in 1896 as "Italy's last military adventure in the area" escapes me. The Libyan campaign in 1912 was much closer geographically and is more recent. It was also quite successful for the Italians (my grandfather was a conscript in that army - I think the experience strongly encouraged his immigration to the States...)
Italy also briefly occupied part of the former Ottoman territories as a member of a multinational force post WWI.
Not to mention that Italy beat the crud out of the Ethiopians and reoccupied the country in 1936 - 40 years after the battle of Adowa.
