For example: to have diplomatic initiatives to diffuse the tensions between ethnic groups and encourage peacekeeping initiatives between these rival groups; to introduce positive information to counter the negative information that is being spread; to have an international arms registry that deals with specific arms, which would go a long way to adding a measure of transparency and accountability where there are military organizations.

Can we draw the following conclusion?
Where there are military organizations it is best to have peacekeeping initiatives between rival ethnic groups.
Yes
