To draw on a carrots and sticks analogy, I would say that we must have sticks to threaten with legal action the Somalia diaspora that are misbehaving and are part of the problem, then we need to focus on what carrots we have to incentivize good behaviour there.
Some of the best governance I've seen across Somalia, I would say, has tended to occur at the municipal level. That is where, like everywhere else in the world, the practical day day-to-day things happen, like who's going to pick up the trash and who's going to run the market, and is the school going to open? Municipal government tends to attract really practical, pragmatic, people-oriented leaders. Not always, as we've had some really bad mayors there, but we've also seen some really good ones.
I would not focus too many resources there, because once you start to flood an area with foreign aid, you end up attracting the wrong elements. But with very calibrated support to those local authorities, that could start to create islands of stability. We may end up seeing Somalia as really a league of city states, little by little, rebuilding itself with towns and cities, and increasingly governing themselves effectively.
