The goal of TPLF's invasion of Amhara land is Revenge & Destruction: It knows it can't consolidate holding long.
It is obvious TPLF can't advance anywhere other than raiding some of the north most areas of Amhara. The irrational behavior of TPLF is directed at destroying Amhara area infrastructure out of pure evil and jealousy, steal Amhara people property, and kill innocent Amhara people out of bitter hate. What TPLF does not care and what every dying Tigre rag tag rebel does not know is they are blowing up the bridge for the future of Tigres to live in peace with next door Amhara people.
