At stake is the power of being the legitimate government. A conflict is fought out with weapons and machinery that needs oil. Diamonds can be used to finance these purchases. In that sense, diamonds are really a prisoner of war of the conflict. If diamonds are found on the field, they will be sold.
Diamonds bring prosperity in a lot of producing countries.
The economies of South Africa, Namibia or Botswana depend in an important way on the diamond industry. The goal is indeed to end the conflicts. Because the only difference between a diamond and a conflict diamond is the conflict. End the conflict and there are only diamonds, diamonds that bring prosperity. For that purpose, a joint action of all industries involved and the international community is required.
