The United Nations was thrust into urgent deliberations on Friday after the United States openly accused Rwanda of driving the eastern Democratic Republic of Congo (DRC) toward a new phase of war. The escalation comes just days after President Donald Trump hosted the leaders of Rwanda and Congo in Washington to secure commitments to a fragile U.S.-brokered peace arrangement.
U.S. Ambassador to the U.N. Mike Waltz issued the most direct warning yet, bluntly declaring before the Security Council: “Rwanda is leading the region towards increased instability and war.” He further vowed: “We will use the tools at our disposal to hold to account spoilers to peace.”
A Rapidly Worsening Battlefield
The renewed surge by the Rwandan-backed M23 rebel group has pushed fighting dangerously close to Burundi’s borders. The rebel advance, according to U.S. diplomats, threatens to derail the Washington peace track that Trump has personally championed. Since January, the conflict has killed thousands and displaced hundreds of thousands, with the latest clashes raising the specter of a broader regional conflagration.
Burundi, long present militarily inside eastern Congo, has now publicly warned that its patience is exhausted. Ambassador Zephyrin Maniratanga told the Security Council: “Restraint has its limits… it would become extremely difficult to avoid a direct escalation between our two countries.” For a region already drowning in militia activity, proxy battles, and mineral-driven violence, Burundi’s threat of direct confrontation marks a dangerous escalatory shift.
Accusations and Counter-Accusations
Rwanda’s U.N. Ambassador Martin Ngoga rejected the allegations, accusing Burundi instead of attacking Rwandan territory. Kigali insists that it neither supports M23 nor seeks conflict with its neighbors, and maintains that Congo itself has violated previous ceasefire commitments. Rwanda says it remains fully committed to the Washington peace agreement reached in Trump’s presence.
Congo, however, forcefully countered this narrative. Foreign Minister Thérèse Kayikwamba Wagner urged the U.N. to hold Kigali accountable, warning: “Impunity has gone on for far too long.” She framed the situation as a defining test for the international order—whether the world would allow a U.N. member state to defy Security Council resolutions with military interference on foreign soil.
Washington’s Peace Deal Under Strain
The resurgence of M23 comes only a week after Presidents Félix Tshisekedi and Paul Kagame met Trump in Washington and reaffirmed support for a U.S.-led peace roadmap. But the timing of the rebel offensive has sparked speculation that M23, long accused of receiving military guidance from Kigali, may have been testing regional resolve.
Ambassador Waltz reinforced this view, telling the Council that Rwanda has had “strategic control” of M23 and its political wing—the Congo River Alliance (AFC)—since the group’s revival in 2021. U.S. intelligence estimates, he said, indicate that 5,000 to 7,000 Rwandan Defense Forces troops have operated alongside M23 in Congolese territory.
Analysis: A Peace Framework in Danger
The crisis threatens to collapse Trump’s most ambitious African security initiative. If Washington cannot enforce its own agreement, U.S. credibility as a peace mediator will suffer. Burundi’s warnings of escalation, Congo’s calls for accountability, and Rwanda’s denials now form a triangular stalemate with potentially catastrophic consequences.
The U.S. sees Rwanda’s alleged actions as a direct challenge—not only to regional stability but to the diplomatic framework crafted in Washington. If Kigali continues to distance itself from M23 while battlefield evidence suggests otherwise, pressure for sanctions or punitive U.N. action may increase.
Meanwhile, the fact that M23 is negotiating separately in Qatar undermines the coherence of the Washington peace process. The fragmentation of talks risks creating multiple, competing diplomatic tracks—something that historically has prolonged conflicts in the Great Lakes region.
For now, the UN’s warnings and the U.S. accusations serve as a stark reminder: the window for preventing a multi-state regional war in central Africa is narrowing rapidly.
