Why don the European Union or United Nations call it genocide?
The UN and EU did not say it isn’t genocide, they said they don’t have sufficient evidence to call it genocide and say they are “tantamount to genocide”. That is probably political obfuscation more than anything, especially fearing triggering actions that must be taken due to the Genocide Convention. We know from being on the ground that even though the killing has slowed for the most part (though there are punctuated moments of village bombings and other attacks) the government of Sudan has brought about conditions calculated to destroy civilian groups, and the fact that they do so through very intentional and even laborious methods of blocking aid and preventing people from moving back to their villages to farm makes the intent very clear. So too does the fact that the airplanes used in bombing are theirs.
