I...legitimately did not expect it to end this way.
Had lunch with an Ethiopian friend of mine some time back and he was filling me on some details about all this stuff.
The overall takeaway I got was this time around there is lot more to Ethiopia than meets the eye (compared to before during the cold war and 90s etc during those strifes and wars).
There is a small but significant and growing middle class and lower middle class that provide buffer obstacle inertia to the traditional power-wielders of each group....compared to before where such middle layers simply didnt exist and didnt really agglomerate anywhere either (everyone was simply rural and poor and there was the few powerful types in the few small towns and cities).
No place illustrates it better now than Addis, the capital, where many groups have come together (over now an appreciable enough of time and experience) to form businesses, neighbourhoods and livelihoods and are well tied in with Ethiopian expat community internationally too.
So pushing around and inflicting harm upon the large populations on polarised tribal basis and being able to dismiss consequences of a developing famine etc is simply not as easy as it once was for tribal leaders etc.
Simply enough conduits have developed now outside of the old power dynamics.
The sheer size of Ethiopia has also changed since the older times, its population is now 125 million or so. That is also a big buffer against easiness of war.
