ABSTRACT
Despite agreements on national and international rules to keep societal cohesion and peace there are serious moments of social unrest in which groups attack other groups with the purpose of annihilation and with the final objective of excluding them from political life. Those violent exclusions acquire an ethnocentric justification due to racial prejudice, religious hatred or economic competition. The international recognition of those conflicts as genocide and internal strife has prompted the creation of United Nations-led peacekeeping forces or ad hoc international committees that try by diplomatic means to bring together parties that fundamentally disagree on rules of common living and provide national and international insecurity.
