The statement that best describes the comparison between the 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.
The Rwandan genocide, which took place in 1994, saw a delayed international response, with many nations and organizations failing to recognize the severity of the situation until it was too late. In contrast, the 9/11 attacks in 2001 elicited an immediate global reaction, with a swift coalition response led by the United States. The differing reactions can be attributed to factors including the visibility of the events, geopolitical interests, and the international context of the time.
