Yupp Abiy is in bed with Egypt & their allies, I also suspect it was him who was behind the assassination of the chief engineer of the GERD project.
Check this out, they're on a collision course with the TPLF, Tigray will trigger article 39 sooner than later.
Why would PM Abiy or even Egypt want to kill the chief engineer of the GERD project? What are they gonna achieve with this act? Everybody knows you can't stop any project let alone GERD by killing an engineer. Engineers are technical people and can be replaced pretty much easily by other engineers. So how can any entity that wants to stop the GERD projects targets a technical professional and hopes to stop the project? It just doesn't make any sense for Egypt or PM Abiy to get rid of an Engineer.
The most plausible explanation is that the old TPLF guard who have been forcing the Engineer to order non-existent machinaries and building materials could be behind his assassination because most probably he very well knew the top TPLF looters by name.
