If the countries of the Horn of Africa are to prosper, they must cultivate an outlook that turns their borders from walls into bridges.

Introduction

The Horn of Africa is currently experiencing significant geopolitical realignment, characterized by two opposing coalitions. On one side, an alliance of Egypt, Somalia, and Eritrea seeks to contain Ethiopia’s ambitions. In contrast, a United Arab Emirates-backed bloc has formed between landlocked Ethiopia and the self-declared republic of Somaliland. This new rivalry is unfolding against the backdrop of a widening civil war in Sudan, the militarization of the Bab el-Mandeb Strait, and a new Red Sea security initiative led by Saudi Arabia. Collectively, these dynamics raise serious concerns that regional conflicts could escalate into broader proxy wars. 

The Roots of Instability: Ethiopia’s Quest for the Sea

The persistent instability in the Horn of Africa stems from unresolved historical political problems, consistently compounded by the interference of external powers. Many analysts argue that the primary driver of current volatility is the race to secure direct sovereign access to strategic maritime choke points. 

This dynamic became fully evident on January 1, 2024, when Ethiopian Prime Minister Abiy Ahmed and Somaliland President Muse Bihi Abdi signed a contentious Memorandum of Understanding (MoU). The agreement would lease a 20-kilometer stretch of Somaliland’s coastline along the Gulf of Aden to Ethiopia for fifty years, allowing Ethiopia to build a naval base and secure direct sea access. In return, Ethiopia pledged to become the first UN member state to formally recognize Somaliland’s independence.

 The Federal Government of Somalia vehemently rejected the MoU as an existential threat to its sovereignty and territorial integrity. In response, Mogadishu moved to strengthen its ties with Cairo, culminating in a bilateral security pact and a maritime defense cooperation agreement. Egypt pledged to deploy up to 10,000 troops to Somalia under the new African Union Support and Stabilization Mission in Somalia (AUSSOM) to replace the departing Ethiopian peacekeepers. Egypt’s engagement includes direct arms supplies and positioning its forces along Ethiopia’s borders. 

Concurrently, a cooperation agreement was formalized at a trilateral summit in Asmara in October 2025, establishing a de facto alliance among Egypt, Somalia, and Eritrea. In follow-up talks in May 2026, Egypt reinforced its stance that the governance of the Red Sea must be restricted to littoral states, a move designed to isolate Ethiopia. Addis Ababa interpreted this alliance as a strategy of strategic encirclement. 

Despite the heated rhetoric, quiet diplomatic backchannels remain open between Somalia and Ethiopia. Following the late-2024 Ankara Declaration, brokered by Turkey, delegations from both countries have held intermittent talks. On June 29, 2026, Prime Minister Abiy and Somali President Hassan Sheikh Mohamud met in Ethiopia to improve interstate relations, emphasizing mutual trust, economic cooperation, and joint counter-terrorism operations against Al-Shabaab as the foundation of their “shared destiny.” 

Saudi Arabia’s New Security Framework

On July 30, 2026, Saudi Arabia announced a multinational maritime defense framework to protect the shipping lanes in the Red Sea, Bab el-Mandeb Strait, and Gulf of Aden. This move was prompted by the deteriorating security situation, particularly the Houthi maritime blockade targeting Saudi shipping on July 20. Although the initiative was backed by 14 governments and involved deliberations with 43 countries, the resulting coalition was less broad than anticipated. 

Riyadh is actively flexing its political and military muscle to ensure its security, a move tangibly demonstrated by the historic Mecca Joint Defence Agreement signed on August 7, 2026, between Saudi Arabia, Turkey, and Pakistan. These powers have established mechanisms for coordinating air defense, unmanned systems, electronic warfare, and joint exercises. 

Notably, analysts argue that Riyadh concluded that including Ethiopia in this framework would carry excessively high strategic costs, embroiling the coalition in pre-existing disputes such as the Nile River conflict and the Somalia-Somaliland territorial issue. Furthermore, as Saudi oil exports transit through Egyptian-controlled maritime chokepoints, Cairo holds substantial diplomatic leverage over Riyadh. Consequently, Saudi Arabia has prioritized its warm relationship with Egypt over its collaboration with Ethiopia. This has created significant concern for Ethiopia, a nation of over 135 million people that depends on Red Sea corridors for more than 95 percent of its international trade. 

Sudan’s Proxy War and Gulf Rivalries

The war in Sudan, now in its fourth year, has evolved from a local conflict into a volatile regional proxy war. Saudi Arabia and Egypt support the Sudanese Armed Forces (SAF), led by General Abdel Fattah al-Burhan. Conversely, the United Arab Emirates, despite international sanctions, has thrown its considerable political and financial networks behind the rival Rapid Support Forces (RSF), led by Hemedti. 

This division is directly reflected in the politics of the Horn of Africa. Allegations persist that the Ethiopian federal government, a key UAE partner, is directly involved in the proxy conflicts. Reliable sources indicate that Ethiopia established a covert military training base in the Benishangul-Gumuz region to train thousands of RSF fighters, reportedly financed and logistically supported by the UAE. This has turned Western Ethiopia into a rear base for the war in Sudan. 

This mobilization caused immediate alarm in Eritrea, which borders Sudan and is at the center of the anti-Ethiopian security framework. In response, Eritrea reinforced its alliance with Saudi Arabia and Egypt to strengthen its border security and prevent RSF-driven instability or the expansion of Emirati influence. This has added a dangerous border security dimension to the existing tensions with Addis Ababa. 

Djibouti’s Calculated Neutrality

Amid intensifying regional militarization, the small nation of Djibouti strives to preserve its stability through a calculated foreign policy. By leveraging its strategic location, Djibouti hosts military bases for numerous rival global and regional powers, including the United States, France, Italy, Japan, Saudi Arabia, and China. A central pillar of its policy is maintaining sovereign neutrality toward all external stakeholders while cooperating with them against non-state terrorist entities. 

While Djibouti has previously permitted foreign bases to launch operations against piracy and terror groups, the recent Red Sea crisis has prompted a stricter diplomatic line. Djibouti prohibited the US and its allies from launching offensive strikes against Houthi forces from its soil. It maintains that the Houthis, who control the capital Sana’a, function as quasi-state actors and not merely as non-state terrorist groups. By asserting this neutrality, Djibouti prevents its territory from becoming an active war theater or a target for Houthi retaliation. This policy is an act of self-preservation, ensuring that its critical port infrastructure—an indispensable economic lifeline for both Djibouti and Ethiopia—continues to operate without disruption. 

Ethiopia’s Internal Crisis and Regional Ambition

Ethiopia is entrenched in a severe crisis driven by the leadership’s political myopia. The reform trajectory launched by the EPRDF lost its direction, fostering a climate that accommodates narrow, sectarian interests. The power struggle between the Prosperity Party and the TPLF led to a war in 2020. Although the Pretoria Agreement provided a reprieve, the underlying crisis remains unresolved. Tigray’s constitutional status has not been restored, displaced persons have not returned home, and essential services are lacking. 

Beyond Tigray, armed groups like Fano and the Oromo Liberation Army (OLA) continue to mount violent resistance against the federal government, placing national security in grave jeopardy. However, the factor that exacerbates Ethiopia’s internal crisis the most is the Prosperity Party’s aggressive ambition to secure direct sea access and port ownership. Following the Somaliland initiative’s diplomatic setback, this campaign turned its gaze toward Eritrea, with ongoing diplomatic and military preparations that continue to alarm the region. 

Eritrea’s Central Role and Growing Tensions

Eritrea plays an active and intricate role in the current geopolitical landscape. Once a wartime ally of the Ethiopian federal government during the Tigray War, it is now in a state of severe confrontation with Addis Ababa, finding itself at the center of regional efforts to contain Ethiopia’s ambitions. 

Following the October 2025 Asmara Summit, Addis Ababa views the alliance with Egypt and Somalia as a hostile encirclement maneuver aimed at countering the Grand Ethiopian Renaissance Dam (GERD) and neutralizing Ethiopia’s sea-access ambitions. A direct military standoff is emerging along the Ethiopia-Eritrea border. In March 2026, Ethiopian Foreign Minister Gedion Timotheos accused Eritrea of forward-deploying troops, calling it an “act of overt aggression.” Eritrea’s Information Minister Yemane Gebremeskel rejected this accusation as a pretext for war. 

Tensions have also spilled over into covert operations in the region. An August 2026 report by the Ethiopian News Agency alleged that Eritrea formed an operational coalition with Ethiopian opposition forces, including the TPLF. 

Conversely, a 2026 investigative report highlights a quiet diplomatic thaw between Eritrea and Djibouti, two states with nearly two decades of frozen relations between them. Rapprochement could lead to strategic port coordination, potentially altering maritime security governance in the Bab el-Mandeb Strait. 

The US–Eritrea Rapprochement and Ethiopia’s Anxiety 

Driven by emerging security vulnerabilities in the Red Sea, the United States initiated a diplomatic pivot toward Eritrea in 2026. To counter Iranian influence and Houthi maritime interdictions, Washington is actively seeking to use Eritrea’s roughly 1,000-kilometer Red Sea coastline. To this end, the US has moved to ease the comprehensive sanctions previously imposed under Executive Order 14046. 

Through the quiet mediation of Egyptian President Abdel Fattah el-Sisi, Senior US Advisor Massad Boulos held direct talks with President Isaias Afwerki in Cairo. The discussions centered on sanctions relief in exchange for expanded diplomatic engagement and maritime security cooperation in the region. While US Secretary of State Marco Rubio conveyed a message marking a “new era” of relations in May 2026, the realignment faced scrutiny from human rights advocates over Eritrea’s compulsory national service system. 

For Eritrea, US political support is an opportunity to end decades of international isolation and to deter any Ethiopian attempts to seize its territory. 

In Ethiopia, this warming relationship is a source of deep anxiety. Addis Ababa views this as a clear signal that Washington does not support its efforts to secure maritime access through forceful means. The combination of the Saudi-led maritime coalition and the US pivot toward Asmara effectively marginalizes Ethiopia and risks accelerating its isolation. 

Analysts indicate that an emerging US–Eritrea partnership raises fears in Addis Ababa that Ethiopia’s decades-long historical relationship with the United States is becoming complicated, potentially accelerating Ethiopia’s regional isolation. 

Eritrea’s Strategic Policy Choice: A Call for Internal Reform

Any Ethiopian request for port access can be legitimately addressed through international law and diplomatic negotiations. However, when such initiatives violate Eritrea’s sovereignty, they lead to conflicts. The international community must reject Ethiopia’s coercive posturing, and Eritrea’s right to self-defence is legitimate. However, exercising this right requires not only military readiness but also sophisticated political and diplomatic statecraft. 

At this critical juncture, relying solely on isolation and internal repression is not a viable long-term national security strategy. For decades, the Eritrean government has operated under a centralized governance model, rooted in domestic control. It shelved the ratified constitution, rejected political pluralism, paralyzed the national economy, and suppressed dissent. This has bred internal grievances that weaken national unity. A government alienated from its citizens cannot effectively confront external threats. 

A country facing existential threats cannot rely solely on military power; its ultimate defense rests on its people’s resolve. By treating a large segment of its population as adversaries, the PFDJ regime has fought a war on two fronts: one internal and one external. This is strategically unsustainable. Therefore, the Eritrean government must take the initiative to launch an unconditional national dialogue, establish an inclusive transitional administration of national unity, and guide the country toward constitutional governance. Releasing all prisoners of conscience is a critical first step. The regime must also extend a hand of peace to the Eritrean opposition. This requires abandoning the dismissive policy of demanding citizens “fill out repentance forms.” 

Concurrently, Eritrean opposition groups must forge a united front with like-minded internal movements, uniting around a minimum common program focused on inclusive transitional governance and a transition to a constitutional democracy. By coalescing around a shared baseline platform, diaspora organizations can mobilize Eritreans abroad, conduct impactful diplomacy to pressure the government to accommodate dissent, and draft post-transition policy blueprints, compelling the regime in Asmara to take them seriously.

 An Eritrea governed by constitutional rule of law and anchored in national reconciliation would deny foreign powers the opportunity to exploit domestic fractures in the country. An inclusive, legitimate government can engage the international community from a position of moral high ground to advocate for peace. 

Eritrea possesses every sovereign right to take all necessary measures to avert war. However, the primary focus must be on proactive, skilled diplomacy capable of diffusing conflicts before they erupt. This requires exploring tactical and strategic alliances—not as instruments of war, but as deterrents against aggression—underpinned by inclusive, consensus-driven governance rather than unilateral decision-making. 

A unified Eritrea that embraces its populace can put pressure on regional bodies, such as the IGAD and the African Union, to move beyond rhetorical statements, apply firm diplomatic pressure on Ethiopia, and insist that Ethiopia pursue its maritime commercial aspirations strictly in accordance with international law rather than through military coercion. 

Equally, historical responsibility requires citizens of both Ethiopia and Eritrea—both at home and in the diaspora—to refrain from warmongering and inflammatory rhetoric. Social media platforms should serve as instruments of peace, dialogue, and reconciliation rather than conduits for amplifying hostility. The IGAD, African Union, and international stakeholders must maintain active diplomatic pressure to ensure a peaceful settlement. 

The Imperative of Regional Cooperation: From Walls to Bridges

The geography and history of Eritrea, Ethiopia, Djibouti, Sudan, and Somalia are irrevocably interlinked. These nations are obliged to work toward the common good; failing to do so invites their mutual destruction. Their foremost priority must be consolidating domestic and regional peace while advancing regional integration. This requires a collective rejection of proxy warfare and extreme caution to avoid falling into the geopolitical traps set by external powers. 

Regional disputes must be resolved peacefully through dialogue, traditional mechanisms, and international mediation. Ethiopia, Somalia, and Sudan must address their internal crises within their constitutional frameworks. Rejecting political pluralism and using violence against citizens generates instability that inflames the wider region. 

If the countries of the Horn of Africa are to prosper, they must cultivate an outlook that turns their borders from walls into bridges. Rather than remaining barriers of division and flashpoints for conflict, borders must become corridors of opportunity, fostering trade, cultural exchange, and shared economic development. This paradigm shift is not an unattainable ideal; it is the only realistic foundation for averting recurring crises and ensuring lasting regional stability.
