The statement that best describes the comparison between international reactions to the Rwandan genocide and the 9/11 attacks is:
The international community immediately responded to 9/11 but did not react to Rwanda until after the genocide occurred, based largely on differences in geography, culture, and political systems.
This statement accurately reflects the contrasting responses: the profound, swift international reaction to the 9/11 attacks, contrasted with the delayed and inadequate international response to the Rwandan genocide, which saw minimal intervention during the crisis despite the magnitude of the atrocities. Factors such as geography, political implications, and cultural ties influenced these differing reactions.
