Theyve been sanctioned by the us, which is basically a seal of approval for me. Other than that, i think theyve boosted literacy rates by like 10 percent. They also seem to socialist/state capitalist, somewhat like belarus. Dunno anything else about them tbh.
Another good thing about it is its capital city is full of pleasurable tingles/frisson.
If you have more specific questions about Eritrea, I'll ask my neighbours.
