My understanding is limited but from my current knowledge (which might be completely wrong):
The RSF is compromised of an Arab force backed by the UAE who are pretty racist and want to install an Arab superiority regime and are mass raping + murdering black people. They are 100% committing a Genocide.
The current Sudanese military (SAF) is backed by Iran (and maybe others). SAF also commit a lot of war crimes but seem to be more financially motivated. SAF seems more into the civil war thing than Genocide, but SAF soldiers are also raping and murdering civilians.
The RSF is the successor to the janjaweed militia, which carried out a genocide in Darfur just 20 years ago against non-Arab ethnic groups such as the Fur, Masalit, and Zaghawa. At the time, a mass movement emerged in the United States—led by the Save Darfur coalition, which comprised nearly 200 organizations—mobilizing worldwide protests and bringing out prominent celebrities, including then-Sen. Barack Obama and George Clooney, and demonstrators in the hundreds of thousands.
A powerful U.N. Security Council arms embargo, sanctions regime, and referral to the International Criminal Court ensued, resulting in the first—and only—arrest warrant for genocide against Sudanese leader Omar al-Bashir, while an eventual joint U.N.-African Union peacekeeping force was dispatched to the region; it was later withdrawn in 2021.
Our inquiry also concluded that the RSF is receiving direct military, financial, and diplomatic support from the United Arab Emirates. This finding is also backed by the U.N. Panel of Experts on Sudan, who found credible evidence of the UAE providing heavy weaponry to the RSF, as corroborated by further investigative reporting. In December 2023, a group of U.S. members of Congress sent a letter to the Emirati foreign minister urging an end to the UAE’s provision of military support to the RSF. This May, legislation was introduced to stop U.S. arms exports to the UAE until it ceases its support to the RSF.
