Ya, Rwanda is a lesson for all others. Unfortunately, as you said the prior genocide is the reason for a new future genocide. Unfortunately In Ethiopia currently there is silent genocide on the "Amhara" people which in my opinion will be a reason for the the near future widespread genocide among different ethnic groups of Ethiopia. Therefore developed and democratic countries like the US shall put their maximum effort into stopping the upcoming worst in Ethiopia.
