There are significant differences between Gaza and Sudan though. We do have a better chance of stopping this one.

With Gaza the genocidaires are a key US ally and consequently the US is aiding them and trying to block interventions by the UN and ICC.

With Sudan neither of the belligerents are important to the US. The SAF is backed by Iran and its opponent the RSF/Janjaweed is nominally backed by United Emirates and also backed by warlords with ties to Wagner group.

The RSF is militarily backed by the United Arab Emirates and has profited greatly from selling conflict gold to Dubai, Chad and Russia, which seeks a base on the Red Sea. The RSF has used genocidal violence and mass rape against non-Arab ethnic groups in Darfur and mass atrocities in other regions to gain territory. 

The corruption-fueled Sudanese Armed Forces is backed by Egypt and Iran, with Iranian drones providing recent battlefield momentum. The SAF is dropping barrel bombs on urban neighborhoods, arresting and torturing Sudanese pro-democracy activists in ghost houses, and committing other grave rights violations.
