You shouldn't need to provide links for every topic of general knowledge, like the factual existence of wars that have taken place within living memory or are part of an educational curriculum. Wikipedia is an adequate place to begin researching a topic like that. If you can't see why Rwanda's example is relevant in this context then I urge you become more informed about the topic.

I am actually very familiar with the topic and I am thus aware that one can find many, seemingly contradictory, sources. But thanks anyway.
