For the moment. Its been downhill toward Islam for them ever since Selassie died
I have to disagree strongly with you on this.
In the late 1970s, Ethiopia went Marxist under Soviet and Cuban military “advisers”.
After a dozen or so, they shook this off which led to a religious revival among the Orthodox, Coptic Ethiopian Church and the people. At the same time, their Red Sea state, Eretria, which was Muslim, rebelled.
Eventually, the Eretria’s won their freedom, but have used terrorism against the Ethiopians ever since. Ahmed is finally bringing that to an end.
The country still holds land below the Central Massif (the traditional Coptic Ethiopian highlands) that have a Muslim population, but that is a regional religion. The Muslims are in no way making any headway in the Coptic areas. As far as proselytizing by the sword, that was happening with Eretria, and hence the now (lasting?) peace.
All of this has actually strengthened the Coptic Church. More church growers as a percentage of total population as long as they kept records.
