As I have noted in the opening comment, Blinken is not an African expert. Susan Rice is not an Ethiopian expert; she does not know Ethiopia. She knows TPLF. Linda Thomas, I have never heard of her as Ethiopia expert. Blinken is not even a student of Africa.
So you see, this is how America runs its world diplomacy - with personal power seekers with little knowledge of the task and zero grasp of the complexities and gravity of meddling in the lives other people about whom they possess little or no understanding.
As the result, America has suffered its first diplomatic defeat in Africa - a totally unforced error. The world just learned that America can no more simply dictate its wishes, illusions and arrogance on others at will.
America had no need to accuse Ethiopia on a world body, Ethiopia a founding nation of the League and the UN. America was defeated. Now, Biden must replace Linda Thomas, an incompetent bad news for his global agenda. Biden also needs to advise Blinken to take his time to do his learning curve as the chief diplomat of USA.
The UNSC Ethiopian vote is a clear defeat on the part of America's policy toward Ethiopia if not Africa.
