I think everybody implicitly understands, but does not say, that Somalis can only be ruled effectively through violence--at least in this stage of cultural developlement. Habeshas tend to listen to and heed authority without coercion, especially Amharas, it's part of their culture and history while this is not true for Somalis. I think Ilay's crimes need to be interpreted in the context in which they happened---an unruly, nomadic population with aspirations of forcefully breaking away and who regularly refused government edicts such as taxation, religious difference toleration, and clan peace. So they needed to be smashed up to get them to comply, and that's what Ilay did. People started paying taxes under him and accepted the political reality of remaining with Ethiopia. I would pardon him and let this man rest in peace, in exile.
