"I don't think there is an American party that has the cards to pressure any of the two warring generals in Sudan," says U.S. diplomat.

He added that the Sudanese army has aircraft and artillery but lacks foot soldiers, while the RSF has trained infantry forces but lacks aircraft and heavy artillery. "Whoever has gold and financial resources coming from neighbouring countries must continue the war," he says. The White House said the withdrawal of the SudanESE military from the negotiations in Jeddah was regrettable.
