The United States reacted to Rwanda's genocide of the Tutsi people in the following ways:
1. The U.S. failed to get involved in Rwanda when Tutsi people were being killed. This was a significant aspect of the U.S. response to the genocide as there was a lack of direct intervention during the crisis.
2. The U.S. did not withdraw troops from Rwanda before they could be effective because there were no troops deployed to Rwanda during the genocide.
3. The U.S. did not threaten to invade Rwanda if the genocide did not stop. Military intervention or threats of invasion were not part of the U.S. response to the genocide.
4. The U.S. did not kill Tutsi people while trying to stop the conflict. The U.S. military did not engage in actions that resulted in the killing of Tutsi people during the genocide.
Overall, the United States' response to the genocide in Rwanda was characterized by a lack of direct involvement and intervention during the tragic events that unfolded.
