Call me a conspiracy theorist or off the wall suspicionist, but my deep educated guess is this. Woyane Tigray never planned to take over or loot Amara Land. Woyane Tigray never planned to really take over Oromo land and resources. TPLF always knew what it was facing.
But by making noise in Amara and Oromo, its deep hidden plan and strategy was the take over of the Fertile South from the mouth of Gibie to the foot of Omo.
Consider the fake alliances in EPRDF factional struggle. A good part of so called South siding with TPLF. These are like fool slaves in 19th century who believe their seller Arabs.
Is the South in Deep Sleep or in Deep trance or are they dead drunk with Borde?
Tigray does not need Oromia or Amara - they are too big to swallow. They are after the smaller meats and chuck they want eat up.
TPLF strategy is put Oromo in permanent chaos using Somalis and take over the South nicely and silently. Keep watching.
SOUTH - WAKE UP !! I AM HORUS, A LOT OF TIMES, I SEE WHAT IS ON THE HORIZON !
