Ethiopia Insight published on 2 September 2021 a commentary titled "TPLF-OLA Alliance Is a Prelude to Tigray's Secession" by Marishet Mohammed Hamza, Graduate Institute of International and Development Studies in Switzerland.
The author argues that bringing down the federal government is the apparent motive behind the alliance between the Oromo Liberation Army (OLA) and the TPLF, but it is also aimed at preparing for the secession of Tigray Region from Ethiopia. The idea is to support the OLA's entry into power, obtain approval from an OLA-dominated government for a referendum on secession, and then seek the independence of Tigray.
