Who is to blame for Rwanda

the people who were in the war (Hutu and Tutsi) and the United States. The Hutu are to blame for killing their own kind and commiting genocide against Tutsi, and killing those who didnt want to help fight. The Tutsi are to blame for accepting favortism and staying in government by force until the Belgians left, and not attempting to compromise and killing those who wouldnt fight. The United States is to blame for not even attempting to help stop the genocide and not sending in troops to those who wanted to help (Dallaire).
