US Sudan Diplomacy Backfires, Leaving Washington Isolated

Following more than three years of attempting to address the devastating conflict in Sudan, United States diplomacy has reportedly reached a critical impasse. During the 81st session of the United Nations General Assembly in New York, Washington intensified its pressure on the Sudanese Armed Forces (SAF) to sign an unconditional ceasefire. However, this latest maneuver appears to have trapped both the US and the SAF in a diplomatic corner, further diminishing the prospects for peace.

Historically, the Rapid Support Forces (RSF)—the militia seeking to overthrow the national army—have been eager to accept agreements that place them on equal footing with the SAF. Despite the RSF’s history of committing genocide and a clear lack of intent to honor peace terms, US officials have frequently characterized the militia as the more “cooperative party.” Consequently, the American pressure campaign this year has focused almost exclusively on the SAF, operating under the mistaken assumption that such tactics would force the military to abandon its campaign to liberate civilians under RSF control.

This strategy ignores the lesson of the past two decades of comprehensive US sanctions on Sudan, which were far more severe than those imposed by either the Trump or Biden administrations. Those sanctions demonstrated that the Sudanese regime possesses the resilience to withstand prolonged American pressure. Despite this, the Trump administration implemented new sanctions against SAF procurement networks in June, followed by chemical weapons sanctions in July without credible investigative findings. By August, the US proposed a UN-wide arms embargo, an update to the Darfur-specific embargo from the early 2000s that the RSF and its allies have routinely violated.

The US initiative for a broadened embargo failed to secure sufficient support in the UN Security Council and faced an anticipated Russian veto. In a concession, Washington agreed to a one-month technical extension of the existing embargo, though analysts predict this will not garner additional supporters.

The climax of this “maximum pressure” campaign occurred last week when the US conditioned General Abdel Fattah al-Burhan’s ability to address the General Assembly on his signature of the ceasefire deal. Critics describe this as diplomatic blackmail, reflecting US frustration rather than SAF intransigence. The ceasefire proposal, initially introduced prior to last year’s UN session, has been blocked by both parties’ reluctance. Fighting parties are unlikely to agree to a deal that merely allows their opponent to rearm, especially when such an agreement could cement the de facto partition of the country—an outcome that benefits the RSF’s desire to formalize its rule more than the SAF’s goal of national unity.

The US State Department recently issued a statement declaring that neither the SAF nor the RSF represents legitimate constitutional governance, arguing that both sides rule solely through force. While this may be legally accurate in the long term, it was viewed as a poor tactical move to encourage immediate disarmament. Instead, it appeared to serve as a justification for barring al-Burhan from speaking at the UN.

This decision drew sharp criticism for breaching diplomatic protocol and creating inconsistencies, particularly as leaders from other African military juntas and an Iranian delegation were granted visas. Observers suggest the US may be escalating pressure toward regime change, a move that has isolated Washington from Western, Arab, and African coalitions advocating for a comprehensive peace process.

Nations including Saudi Arabia expressed quiet disappointment, with Riyadh warning it would review its participation in the US-led Quad initiative. Rather than achieving progress since announcing its peace ambitions last summer, the Trump administration seems to be repeating the errors of past peacemaking efforts by relying on diplomatic coercion rather than strategic engagement. The intended isolation of the SAF has instead ricocheted onto the United States, which now faces the reality that re-engaging with all belligerents is essential not only to preserve its diplomatic standing but to save lives in Sudan.
