Well if the Hutus were attacking across the border into Rwanda and the Congo failed to police them this would be totally justified.
However nothing ever seems cut and dried in Africa.
Agreed. It never is. It seems the sitting government in Congo has a rebellion on it's hands from former allies. It's reported the rebellion is backed by Rwanda and Uganda. With Angola, Namibia and Zimbabwe backing the Congo. It's a tinderbox and people are playing with matches.
