In the volatile Horn of Africa, where borders have long been battlegrounds, Ethiopia and Eritrea are once again trading barbs that have raised alarms about a potential slide back into war. Landlocked Ethiopia’s persistent push for access to the Red Sea through Eritrean territory has ignited a fierce diplomatic standoff, with leaders on both sides invoking history, sovereignty and survival in rhetoric that echoes their bloody past.
The tension, simmering since a fragile 2018 peace deal, has escalated in recent months. Ethiopian Prime Minister Abiy Ahmed, speaking at a recent event, reiterated his nation’s “irreversible” need for sea access, framing it as essential for Ethiopia’s growing population and economy. Eritrean officials, in turn, have dismissed these claims as “irredentist” threats, warning that any aggression could plunge the region into chaos.
As of 23 November 2025, no shots have been fired along the shared border, but the war of words has experts worried. “The missteps here could lead to a renewed conflict,” said a report from the Soufan Center, a U.S.-based think tank, highlighting how proxy tactics and naval ambitions are testing the peace. The stakes are high: A war could disrupt Red Sea shipping lanes, exacerbate humanitarian crises and redraw alliances across the region, involving neighbors like Sudan, Somalia and Egypt.
A history of alliance and animosity
The roots of this discord stretch back more than a century. Eritrea, with its 1,350-kilometer (840-mile) Red Sea coastline, was an Italian colony from 1890 until World War II, then briefly under British administration before federating with Ethiopia in 1952. Emperor Haile Selassie dissolved that federation in 1962, annexing Eritrea and sparking a 30-year independence war that ended with Eritrean victory in 1991. A referendum formalized secession in 1993, leaving Ethiopia without direct sea access.
The two nations enjoyed a brief honeymoon in the mid-1990s, but a border dispute erupted into a devastating war in 1998. More than 100,000 people died in trench warfare reminiscent of World War I before a 2000 peace agreement, brokered in Algiers, established a boundary commission. Ethiopia rejected the commission’s ruling, leading to two decades of “no war, no peace” stalemate.
That changed in 2018 when Abiy, newly in power, extended an olive branch to Eritrean President Isaias Afwerki. The leaders signed a declaration ending hostilities in Asmara, Eritrea’s capital, reopening borders and restoring ties. Abiy’s efforts earned him the Nobel Peace Prize in 2019. The thaw allowed joint military action during Ethiopia’s 2020-2022 civil war in the northern Tigray region, where Eritrean forces allied with Ethiopian troops against Tigrayan rebels.
But the alliance frayed post-conflict. Disagreements over Tigray’s disarmament, border demarcations and Ethiopia’s economic woes fueled mistrust. By 2023, Abiy openly declared sea access an “existential” issue for Ethiopia, whose population has ballooned to over 120 million and is projected to reach 200 million in 25 years.
Ethiopia push for the sea
Abiy’s administration has amplified calls for Red Sea access, focusing on Eritrea’s southern port of Assab, just 60 kilometers (37 miles) from the border. In September, Abiy described Ethiopia’s loss of sea access as a “mistake” to be “corrected tomorrow.” Army chief Field Marshal Birhanu Jula echoed this in October, questioning how Eritrea’s smaller population—estimated at around six million—could override Ethiopia’s needs. “We will strengthen our defense forces, speed up our development and secure a sea outlet,” Birhanu told troops.
Other officials have been blunter. Ethiopia’s ambassador to Kenya, retired Gen. Bacha Debele, called Assab “Ethiopia’s wealth” in a November interview, insisting it would be reclaimed “by force.” Maj. Gen. Teshome Gemechu, head of military diplomacy, said ownership of Assab was a “survival interest worth paying any price for.” Gen. Desta Abchie, from the army’s engineering department, told officers the military was “toiling day in and day out” toward Red Sea access.
These statements come amid Ethiopia’s broader regional maneuvers. In January 2024, Ethiopia signed a memorandum of understanding with the self-declared republic of Somaliland for port access, a deal that angered Somalia and drew international scrutiny. Abiy has since pivoted back to Eritrea, calling for “international mediation” in October 2025 to resolve the dispute peacefully. “Ethiopia has no intention of going to war with Eritrea,” he said, urging economic integration instead.
Yet, critics see mixed signals. In March 2025, Abiy publicly ruled out war, but the rhetoric persists. Ethiopia’s state media has fueled the narrative, with ETV broadcasting commentaries on the “unjust loss” of ports and showing protesters with signs reading “Assab is ours” or “From the dam to the sea,” linking it to the Grand Ethiopian Renaissance Dam on the Nile.
Eritrea defiant stance
Eritrea, often dubbed the “North Korea of Africa” for its isolationist policies, has responded with restraint but resolve. Information Minister Yemane Gebremeskel has used social media platform X to reject Ethiopia’s claims as a “toxic agenda” of irredentism. In September, the ministry warned that legitimizing “flagrant aggression” crossed a “red line” with serious consequences.
In a rare November statement, the Eritrean army cautioned Ethiopian leaders against “plunging the Ethiopian people into a quagmire,” adding that crossing the red line meant “plunging into an abyss from which they will never have a second chance.” State media editorials accuse Ethiopia of reviving “issues settled decades ago” and inciting conflict.
President Isaias, in power since 1993, has remained largely silent publicly, but Eritrea’s mandatory national service—often indefinite—ensures a ready pool of trained youth. Pro-opposition outlets like Asena TV report movement restrictions on troops, signaling heightened alertness. Even critics of Isaias abroad, such as Radio Erena in Paris, have condemned Ethiopia’s “provocative statements,” urging Eritreans to unite against external threats.
Boots on the ground and broader ripples
No major troop movements have been reported along the 1,000-kilometer (620-mile) border, but both sides are bolstering capabilities. Ethiopian state TV has aired graduations of thousands of cadets, with Lt. Gen. Hachalu Sheleme boasting of “tens of thousands” joining the army—a “message to our enemies.” In September, President Taye Atske Selassie promoted 66 officers, praising the military’s “elaborate” preparedness. Parades showcase new weapons, including tanks and artillery.
Eritrea, meanwhile, maintains its conscription system, training thousands annually. No public parades, but intelligence suggests quiet reinforcements.
The standoff is reshaping the Horn. Tigray, caught between the two, fears being dragged in. Sudan’s civil war adds volatility, with Eritrean borders tense. Egypt, wary of Ethiopia’s dam, may exploit the rift, while the UAE—backing Abiy—eyes Red Sea influence. A New Lines Magazine analysis warns of “missteps” leading to war, noting Isaias’ proxy tactics and Abiy’s ambitions.
International calls for dialogue grow. Abiy’s mediation plea echoes in UN letters, but Eritrea denies supporting Ethiopian rebels, calling accusations tension-heightening. The Economist notes the threat is “reconfiguring alliances,” with potential to destabilize global trade routes.
For ordinary Ethiopians and Eritreans, weary of conflict, the rhetoric feels like a ticking bomb. “We need cooperation, not conquest,” said one Asmara resident, speaking anonymously for fear of reprisal. In Addis Ababa, a merchant echoed: “Sea access is vital, but war would destroy us all.”
As the Horn braces, the question lingers: Will words give way to weapons, or can diplomacy defuse this powder keg?
