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 captures the key differences in the international response to both events. The 9/11 attacks garnered a swift and unified international reaction, largely due to their immediate impact on global security and the subsequent "war on terror." In contrast, the Rwandan genocide, which occurred over several months in 1994, saw a delayed and inadequate response from the international community, which failed to intervene effectively despite warnings and evidence of escalating violence. The contrasting geographical and cultural contexts, as well as political considerations, played significant roles in how each situation was addressed (or not addressed) by the international community.
