'All too often, Western good-government types don’t understand how the liberalization of Rwanda’s political sphere and open radio airwaves accelerated the genocide.'While it's correct that this played a role leading up to the genocide, we should not forget the context in which this liberization took place: The international community forced the Rwandan government to negotiate with an outside rebel force, the RPF.
At the same time pressure towards democratization helped this rebel group recruit in Eastern Congo.
What we can learn from it is that forcing a government to negotiate with a rebel group while pushing for democracy isn't a good idea.
The efforts to end the m23 rebellion in Congo indicate the international community has learned from it's previous adventure in Rwanda.
