Ilemi triangle has been disputed for a long time one thing that makes the resolution easy is Ethiopia has not laid claim to the territory that would have brought another angle to the dispute.
There are several treaties over this territory I think what SS has done is be the first to deal with the issue, now the ball is in our court to lay claim and hence take this dispute to the UN if we fail to amicably tackle it.
