A surprise collapse by Sudan’s army turns the war in the paramilitary Rapid Support Forces’ favor

In a matter of days, the Sudanese state of Al-Jazirah fell to the paramilitary Rapid Support Forces, which the UN and human rights monitors have directly linked to mass killings targeting ethnic groups elsewhere in the country. The way the Sudanese national army vanished from the capital of Wadi Madani has some experts concerned that a destabilizing military force such as the RSF might overrun the whole country, with potentially huge effects on regional security. The World’s Marco Werman talks with Alex de Waal, a top expert on Sudan at Tufts University, about the Sudanese Armed Forces spectacular collapse in Al-Jazirah, and what role the US could play in staunching the bleeding of this disastrous war.
