We have this story alleging that Rwanda is behind the insurgency in the east of Congo, and we have this story discussing negotiations between the governments of Rwanda and Congo to disband the FDLR militias.
The Democratic Forces for the Liberation of Rwanda (FDLR), are the genocidal criminals who massacred a significant portion of the Rwandan Tutsi population, and once driven from the country, set themselves up in “refugee camps” where their basic food and nature needs are provided for by the UN and NGOs, and have continued to wage genocidal campaigns against Tutsis, both in Congo and Rwanda.
A first step to fixing this is to close down the camps, and considering that the Tutsis have not engaged in mass reprisals in the 18 years since the genocide, these camps are not needed.
As to how to close down the camps? That’s simple, just stop delivering supplies.
