Anti-Imperialism or Pro-Human Rights?

"What Mamdani was hearing was basically the position of most Save Darfur types from 2004 on, as it gradually dawned on the world that a genocide was taking place in western Sudan. Most favored sending United Nations troops to Darfur to replace an ineffective African Union force. Others thought that NATO or even American soldiers would be needed to stop the Sudanese government from murdering its own people and to establish the security that would allow millions of displaced Darfuris to begin returning home. Still others believed that the United States should take military measures short of an outright invasion of Darfur, such as establishing a no-fly zone. The particulars of these prescriptions varied, but what was common to all of them was a basic belief that the United States and its allies had a moral obligation to stop genocide and to relieve the suffering of the Darfuri people.
"For Mamdani, all this was simply imperialism by another name."
