Yeah, it seems everything is going in reverse direction for Tigarus.
Here is why TDF failed:
1/ Failure to keep momentum-After TDF reached Debre-Sina, it took them a while contemplating whether to push forward or wait and see if the Gov would give up and call for reconciliation. At the time Gov was busy mobilizing peasants and buying drones.
2/ Failure to strengthen military cooperation with Other rebels- was it difficult for TDF to send some of its military personnel to Different rebel regions to train and coordinate the war in all corners.
3/ Is it the Drone or mass mobilization by the central gov that becomes hard to overcome, for TDF. If the answer is either of these or both, then TDF need to think 2-3x before resuming or trying to go further to fight- you won’t succeed.
