It's undeniable that Washington and other Western nations are significantly responsible for the fighting in Sudan. The US failed to rein in the country's top generals when mounting tensions between forces led by Burhan and Dagalo indicated that a prolonged conflict was likely to erupt.
Since the explosion of violence in Sudan, the US has worked hard to tamp down the violence, bring a peaceful solution, and provide safe passage for humanitarian aid. The US is doing its part in enabling diplomatic resolution and committing itself to supporting refugees until a permanent agreement is reached.
Each warring side in Sudan is still battling for supremacy over the country, which indicates they're in no way serious about ceasefires or peace talks. If the two continue to see each other as an existential threat, it will be impossible to find the middle ground necessary to stop the fighting and prevent the nation from being destroyed.
There's a 50% chance that more than 10K people will die in the Sudan conflict in 2023, according to the Metaculus prediction community.
