From that Wikipedia (2023-):

- Significantly more than 150,000 total killed

- Estimated 522,000 children dead due to malnutrition

- 8,856,313 internally displaced

- 3,506,383 refugees

The other complication is the surprising contributions of various African countries. Ethiopia had supported the RSF until 2024, and Kenya hosted an RSF conference in Feb 2025. Haftar in Libya supported RSF before the war, but may have changed positions as his Russian backers turned against the RSF in 2024. The RSF also has some ties to rebels in South Sudan as well as in Chad. Chad in particular gave shelter to the RSF at the behest of the UAE, but has also seized arms shipments that were intended for the RSF. Russia as noted was sympathetic to the RSF until mid-2024, when they switched sides.

When the war initially broke out, some articles in The Economist seemed somewhat agnostic between the two sides, noting that both had serious corruption issues and had committed many abuses. But as the war has progressed, the RSF seems to have revealed itself to be the far more vicious faction, and the red E along with the rest of the Western media now sees their advances as a tragedy. Unfortunately, the one constant here is the general failure of foresight among nearly all countries of the global North (whether aligned with the West or Russia) getting involved in Africa. If the brutality of the RSF had been better anticipated in 2023, the current situation might have been prevented.

It's also likely that the US is kept at bay by trading UAE acceptance of Israel in return for diplomatic cover and military passivity. The US destruction of Libya has been quite important for the UAE:s ability to supply the RSF as well, a lot of the weapon transports pass through there.

You forgot US and UK.
