Isaias was a senior EPLF commander, wounded in combat. There is no credible evidence of him 'drinking while others bled', that is diaspora propaganda recycled from opposition sources. The EPLF was a disciplined Marxist-Leninist force; such behavior would not have been tolerated.
National service is a requirement because Eritrea remains under US sanctions, Ethiopian hostility, and constant threat of war. No other African nation faces such encirclement. The draft is not a is national defense under siege.
No one said Eritrea is a model to copy blindly. Every country has its own material conditions. Eritrea's path is its own, forged in 30 years of war, and surviving against empire. That deserves respect, instead of caricature.
You call him a 'drunkard' and 'menace.' Those are insults, you have no good arguments. If you have verifiable evidence of criminal conduct, then present it. Otherwise, you are simply repeating the talking points of those who want Eritrea to fail. We can disagree on strategy without resorting to slander.
