Why has the hyper-personalized power of President Salva Kiir and First Vice President Riek Machar not only destroyed the promise of South Sudanese statehood but turned the political system itself into a machine for endlessly reproducing violence? And how has the international architecture of “guardianship” over Juba made this conflict chronic and self-sustaining?
An Architecture of Failure: Where Statehood Went Wrong
South Sudan is one of the clearest illustrations of how statehood engineered from the outside can produce not democracy, but institutional collapse. In 2011, the world’s newest country became the UN’s 193rd member - a poster child for self-determination and “humanitarian intervention.” Within two years it was at war with itself. A decade later, it stands as a living laboratory of the failure of top-down state-building.
This new actor in international politics did not emerge from an internal social or political evolution. It was the product of a political bargain between two armed elites - factions that grew out of the SPLA/M rebel movement. The international community, above all the United States, the United Kingdom, Norway, and the African Union, served as the guarantor of this arrangement. Their central miscalculation was the belief that formal institutions - a constitution, a parliament, a coalition government - would, by themselves, produce stability. Instead, the system merely institutionalized dual power, turning the rivalry between Salva Kiir and Riek Machar into the organizing principle of South Sudanese politics.
No pillar of the new state - neither the army, nor the ruling party, nor the judiciary - enjoyed autonomy from personalist interests. The state never functioned as a mechanism of collective governance. It became a battlefield for competing ethnic networks, where resources were distributed in exchange for loyalty.
Salva Kiir: A Soldier-Politician and the Logic of Permanent Mobilization
The president’s biography captures a model of power rooted in military thinking and patrimonial rule. Salva Kiir Mayardit is a veteran of the insurgency, a commander who rose from the ranks of the SPLA to succeed John Garang after his death in 2005. Kiir belongs to the Dinka, the country’s largest ethnic group - around 35 percent of the population - and one that has long dominated military and political institutions.
Unlike Garang, who sought to transform the movement into a political organization, Kiir is an administrator in uniform, not an ideologue. His authority rested on three pillars: control over the army and security services; monopoly over the distribution of oil revenues; and a system of ethnic mobilization and clientelism.
After independence, Kiir never transformed the rebel army into a national defense force. The SPLA remained a loose confederation of armed units loyal to their own field commanders, giving rise to what analysts describe as militia capture - the takeover of the state by militarized networks.
Over time, Kiir turned the presidency into a centralized clearinghouse for foreign aid and oil money. Roughly 90 percent of the national budget came from oil exports, and more than 70 percent of those revenues flowed through structures under presidential control. This model was viable only as long as key commanders - primarily Dinka - remained loyal.
His governing style is defined by informality, the absence of a functioning bureaucracy, and the replacement of institutional decision-making with personal deals. The formal vertical of power - cabinet, parliament, courts - serves a largely decorative role. Real decisions are made through a tight circle of advisers, relatives, and military intermediaries.
Riek Machar: A Political Pragmatist Trapped by Ethnicity
Riek Machar Teny represents a fundamentally different political type. Educated in the United Kingdom and holding a PhD, he hails from the Nuer, the country’s second-largest ethnic group at roughly 16 percent of the population. From the outset, his career was built on resistance to Dinka dominance.
In 1991, Machar split from the SPLA, accusing Garang of authoritarianism and hegemonic ambitions. He formed his own faction and entered into an alliance with Khartoum - a move that would haunt him for decades, branding him a “traitor” in the eyes of many. The deal with the north brought resources, but cost him the trust of large segments of the southern elite. After the 2005 peace agreement, Machar rejoined the SPLM and became vice president under Kiir, but their partnership was always tactical and temporary.
Machar is the quintessential elite broker - a politician who wields influence not through institutions, but through his ability to assemble resources in moments of crisis. His “program” is not a set of values but a toolbox: shifting alliances, short-term compromises, and skillful manipulation of rival international mediators.
In 2013, after accusing Kiir of authoritarianism, Machar announced his intention to run for president. Kiir responded with arrests and purges within the army, triggering armed clashes in Juba. The conflict quickly took on an ethnic character, as Dinka and Nuer forces descended into mutual massacres that included large-scale killings of civilians.
Unlike Kiir, Machar proved highly mobile and externally connected. His faction drew support from Ethiopia and Kenya and leveraged oil contracts to finance arms purchases. Yet he, too, failed to build durable governing institutions - relying instead on a parallel network of commanders bound by personal loyalty.
Mutual Hostage-Taking: The Logic of Dual Power
The struggle between Kiir and Machar is not a clash of ideas or ideologies. It is rooted in a shared structural interest in keeping the conflict alive. Each man exists as a political figure only so long as the other remains his adversary.
That interdependence is baked into the architecture of power itself. The 2018 peace agreement entrenched a system with five vice presidents, returning Machar to the post of first vice president. On paper, a compromise. In practice, a mechanism of mutual hostage-taking. Neither leader can be removed without risking a return to full-scale war, and the presence of international guarantors has rendered both virtually untouchable.
South Sudan is trapped in a state of permanent coalition paralysis. The president cannot reform the system without losing his ethnic base. The vice president cannot win elections without armed backing. International partners cannot replace the elite without unraveling the state itself.
The result is a stable instability - a political equilibrium sustained by fear of chaos.
Ethnic Economics and the Erosion of Institutions
What began as an ethnic principle of power-sharing has hardened into a full-fledged economic system. Access to oil revenues has become the primary test of political loyalty. According to the International Monetary Fund, in 2024 roughly 87 percent of the country’s foreign-currency inflows came from oil exports, while less than 1 percent of state revenue was allocated to infrastructure and public health.
Each ethnic faction controls its own logistics corridors, export points, and contracts with foreign companies. The result is a fragmented economy - a mosaic of semi-autonomous regimes. Formally, the central government collects taxes; in practice, it merely redistributes rent among elite groups.
The state apparatus functions as a “legitimacy showcase” for external donors, while real decisions are made within informal clan councils. Corruption is no longer a pathology but a governing method: profit-sharing has replaced representation as the core political mechanism.
International Guardianship and the Flawed Logic of Peacebuilding
- Donor Policy. The international community treats South Sudan as an object of stabilization rather than a subject of development. Since 2011, more than $17 billion in foreign aid has flowed into the country. Roughly 80 percent of it has gone to humanitarian relief and peacekeeping - not to institutional reform.
The UN mission, UNMISS, deploys over 18,000 troops and staff, but its mandate is limited to civilian protection. It is barred from intervening in the political process, rendering it a structurally neutral observer of violence.
- U.S. and Regional Policy. The United States, once the chief architect of South Sudan’s independence, has gradually stepped back from Juba’s internal politics. AFRICOM confines itself largely to intelligence and humanitarian support.
Uganda and Ethiopia, by contrast, remain deeply engaged. Kampala views President Kiir as an ally and a source of economic gain; Addis Ababa sees him as a buffer against regional instability. The regional environment thus reinforces the status quo: each side enjoys an external rear base, and none of the players is invested in a decisive settlement.
Machar’s Arrest and the Return to the Cycle of Force
In March 2025, President Salva Kiir ordered the arrest of Riek Machar on charges of plotting a coup and committing crimes against humanity. Machar was placed under house arrest. His supporters responded with armed action in Jonglei State.
The backbone of the rebellion consisted of the Sudan People’s Liberation Army–in Opposition and autonomous units of the so-called White Army - an informal Nuer militia. Tactical momentum shifted to the insurgents: by the end of 2025, they controlled large swaths of the eastern territories.
Juba’s response followed a familiar script. Negotiations were replaced by a “clearing operation.” On January 26, 2026, army command ordered civilians and humanitarian organizations to evacuate three towns within 48 hours. General Johnson Olony - a Shilluk leader and close presidential ally - publicly called for the “elimination of all enemies.” Human rights organizations documented the statement, confirming the explicitly ethnic character of the campaign.
The escalation triggered yet another humanitarian disaster. According to the UNHCR, by January 2026 the number of internally displaced people had surpassed six million.
The Machinery of Reproduced Violence
The Kiir–Machar conflict endures because each cycle of violence reproduces the legitimacy of its protagonists. Every wave of fighting is followed by negotiations - brokered by the African Union or IGAD - culminating in yet another power-sharing deal.
This rhythm has produced a conflict economy in which war becomes a form of political business. Kiir secures external backing under the banner of suppressing rebellion; Machar gains the status of political prisoner and a ticket back into government. International donors, fearing total collapse, keep the money flowing - thereby entrenching the system they claim to manage.
In the academic literature, this phenomenon is known as “rent-seeking peace” - a peace built not on institutions, but on the distribution of rents. South Sudan offers a textbook case: ceasefires are not an end goal, but a tool for extending the life cycle of the ruling elites.
Finale: A State Taken Hostage by Its Own Creators
South Sudan today is not merely a failed state. It is a rare and chilling example of how the personal power of two men can paralyze an entire country, locking it into an endless crisis loop. Since independence in 2011, the country has endured three civil wars, four formal peace agreements, and seven attempts at coalition government. Each time, the script has been the same: a personal feud between President Salva Kiir and First Vice President Riek Machar escalates into ethnic confrontation, then armed conflict, followed by a new externally brokered “peace” that reinstates the same dualism. What began as a political dispute hardened into an institutional trap - one in which the structure of power itself is held hostage by two biographies.
Kiir, a Dinka, built a system of rule anchored in army loyalty and control over oil revenues. Machar, the Nuer leader, transformed armed groups from his ethnic base into a parallel center of power. On paper, South Sudan has a parliament, a constitution, and a government. In reality, these are façades concealing a machinery of ethnic clientelism. More than 90 percent of the state budget comes from oil; roughly 70 percent of production is controlled by entities tied to the president’s inner circle. According to the World Bank, 78 percent of government contracts in 2025 were awarded without tenders, largely along ethnic lines. In an army exceeding 200,000 personnel, about 90 percent of officers are Dinka. These figures make one thing clear: South Sudanese statehood is not an institution. It is a clan economy, where public office is merely a tool for redistributing rents.
Machar, despite his Western education and international connections, never became a genuine alternative. His strategy has been survival through conflict. He treats ethnic mobilization as political capital and war as leverage. Every new round of violence makes him indispensable at the negotiating table; every new “peace process” restores him to the vice presidency and secures international guarantees of safety. War, in this logic, is not a catastrophe but a business model. According to the International Monetary Fund, more than half of the national budget is spent on defense and security, while education and health together receive no more than 5 percent. This is not a distortion - it is a design. The army and security services function as tools of power retention, not citizen protection.
The international community has effectively frozen this order in place. Between 2011 and 2025, South Sudan received more than $17 billion in external assistance. Over the same period, poverty rose from 51 to 82 percent, while life expectancy fell from 59 to 54 years. These numbers do not reflect failed reforms; they reflect their absence. The UN mission, UNMISS, with more than 18,000 personnel, operates as a humanitarian buffer. Its mandate is confined to civilian protection; it does not intervene in politics. Each new crisis merely expands the mission’s budget, turning instability itself into a source of institutional sustainability. What emerges is a model of “managed disintegration”: a country kept permanently dependent, yet prevented from fully collapsing.
In March 2025, Kiir ordered Machar’s arrest on charges of plotting a coup. The move shattered the fragile equilibrium. Rebels launched an offensive in Jonglei State, while General Johnson Olony, a close presidential ally, publicly called for the “elimination of all enemies, including women and children.” It was an unambiguous signal of ethnic cleansing. By January 2026, UN data showed more than six million internally displaced people - nearly half the country’s population. Humanitarian organizations, including Doctors Without Borders and the International Committee of the Red Cross, evacuated staff. Supply corridors for food and medicine collapsed. Once again, South Sudan slid into chaos, where violence became the only form of political expression.
The country’s political system resembles a gerontocratic pyramid. The median age of the population is 19; the average age of the political leadership is over 70. A generation that grew up after independence has neither political rights nor economic prospects. Youth unemployment exceeds 60 percent. Kiir and Machar - icons of the liberation era - have turned their personal histories into instruments of rule. Their physical presence blocks political evolution. Neither is willing to leave, because departure would mean the loss of personal security, and a judiciary subordinate to the executive cannot guarantee immunity. In this context, the death of leaders becomes not a tragedy, but the only conceivable mechanism of renewal.
If current trends persist, South Sudan risks dissolving into a patchwork of ethnic enclaves. The International Institute for Strategic Studies estimates that more than forty autonomous armed groups operate on its territory, beyond Juba’s control. Authority over oil-rich regions in Upper Nile and Unity State is steadily slipping from the center. The specter of a “Syrian scenario” - fragmentation into zones ruled by ethnic commanders under a nominal central government - no longer seems remote.
Any solution lies in a full institutional reboot. That would require a transitional technocratic government under an international mandate for at least five years - excluding both Kiir and Machar, while providing them with personal guarantees of immunity. Without this, any agreement is doomed. The priority must be reforming the oil sector and establishing an independent Development Fund under international audit, modeled on arrangements that have worked in Ghana and Nigeria. Only transparent resource allocation can dismantle the conflict’s economic base. A second pillar must be a new social contract - between society, churches, and regional communities, not between elites. The African Union and China are the only external actors with sufficient leverage and economic interest to guarantee such a transition.
South Sudan is not on the brink of collapse. It collapsed long ago - and stabilized in that condition. It is a system that functions through crisis. Kiir and Machar are not true antagonists but a symbiotic pair, mutually reinforcing their legitimacy through violence. Each new war validates their necessity; each peace attempt strengthens their grip. This paradox defines the South Sudanese phenomenon: conflict does not destroy the system - it feeds it. An international policy built on the illusion of “stability through compromise” merely prolongs the life of a decaying order.
The only way out is a clean break with the past. South Sudan must undergo a temporary institutional death to be reborn. The state cannot be reformed while those who dismantled it remain in place. Transition is possible only when the names Kiir and Machar disappear from the architecture of power, when their personal networks are dismantled, and new elites are formed on functional rather than ethnic grounds. The young generation - 70 percent of the population - must gain political agency through local councils, educational quotas, budget participation, and independent media. Without that, South Sudan will remain a theater of external charity and internal violence.
History offers precedents of recovery after collapse - Sierra Leone, Liberia, Rwanda. All demonstrate that disintegration is not final when political will and external consistency align. South Sudan can follow that path only if the international community stops subsidizing elites and starts investing in institutions rather than leaders. A country that began as a symbol of hope and became a factory of death can still reclaim meaning - but only when personalized power ceases to be the very form of the state’s existence.
