Eritrea’s Large Conscription-Based Military and Strains With Ethiopia Raise Horn of Africa Stability Fears
Eritrea under President Isaias Afwerki continues to field an unusually large military built on compulsory national service, even as relations with neighbouring Ethiopia come under renewed strain. Analysts warn that unresolved disputes and mass conscription are a volatile mix in a corridor critical for Red Sea trade and migration routes.
Eritrea’s decision to keep a disproportionately large army mobilised through open‑ended national service is drawing new scrutiny as tensions with Ethiopia rise again, raising questions about how stable the Horn of Africa really is.
Recent regional analysis notes that under President Isaias Afwerki, Eritrea maintains a military that is very large for a country of its size. The force is sustained by compulsory conscription and national service that can last for many years, not just the fixed terms common in other states. That system has fuelled reports of social strain and prompted many young Eritreans to seek ways out of the country.
For a time, such a security posture was often interpreted as Eritrea’s hedge against isolation and perceived threats along its borders. But Eritrean troops later fought in Ethiopia’s Tigray war and were accused of abuses there, complicating relations with Addis Ababa. As Ethiopia now confronts unrest in regions such as Amhara and Oromia and faces renewed disputes over borders, observers worry that these fault lines could once again pull the two neighbours toward confrontation.
Inside Eritrea, the burden of mass conscription is felt in daily life. Young people face the prospect of indefinite national service, and many families are separated as relatives either serve for extended periods or attempt risky migration through Sudan and beyond toward Libya and Europe. With so many working‑age citizens tied up in the military or leaving, the economy relies heavily on remittances instead of fully using its Red Sea location and diaspora links for domestic growth.
Ethiopia, for its part, is still dealing with the aftermath of the Tigray conflict, including political mistrust and economic costs. A heavily militarised border with Eritrea demands resources and attention that Ethiopian leaders would prefer to devote to internal reconciliation and development.
The stakes extend beyond the two countries. The Eritrea–Ethiopia corridor lies within reach of Red Sea shipping lanes that carry energy supplies and container traffic between Europe, the Gulf and Asia. Renewed fighting or even a sustained period of heightened tension could unsettle investors, complicate port development plans and raise insurance costs for vessels.
The same corridor is also a pathway for migrants and refugees heading north. Any new clashes or crackdowns would likely lead more people to attempt dangerous routes through Sudan toward the Mediterranean, with direct implications for neighbouring states and Europe’s migration policies.
Managing these risks is harder because Eritrea often stands apart from regional diplomacy. Asmara is not deeply engaged in many of the African or Horn‑focused forums that might otherwise offer channels to ease tensions with Ethiopia. Its government frequently presents criticism of its conscription practices and human‑rights record as illegitimate interference, which limits the space for outside mediation.
Signals to watch in the coming months include any visible movement of Eritrean units toward contested border areas, changes in Ethiopian deployments along the frontier, new rhetoric from President Isaias or Ethiopian Prime Minister Abiy Ahmed that portrays the other side as an imminent danger, and how Gulf states and the African Union frame their engagement with both capitals. Together, those factors will indicate whether the region is edging toward another open conflict or finding a way to live with an uneasy balance.
