Who has conceded?
What is Ethiopia's demand? Clear and simple: access to the sea (ደኅንነቱ የተረጋገጠ፣ አስተማማኝ የባሕር በር), which is unimpeded and integrated economic development of the whole region, to make it sustainable and beneficial for all. This were used by the President of Somalia perhaps in almost a year political jargon round trips to many places around the world and the region.
The word used by the Ethiopian side on this regard is that "Ethiopia's demand must be met" (else unacceptable to Ethiopia), to which all the three parties have consented in so far.
In that case Ethiopia can say it is all about "ዬትም ፊጪዉ፣ ዱቄቱን አምጪዉ!" and lean back and watch while things get sorted out.
Who is the biggest loser in all of the show? Isayas Afeworki, as usual.
