THE United Nations Charter repeatedly refers to “disputes or situations” and to “threats to the peace or breach of the peace” but does not use the word “conflict.” In the Kellogg-Briand Pact, however, the parties agreed “that the settlement or solution of all disputes or conflicts of whatever nature or of whatever origin they may be, which may arise among them, shall never be solved except by pacific means.” A “conflict” appears to be less formulated than a “dispute” but more formulated than a “situation.” A “conflict” does not necessarily involve violence as does a “breach of the peace,” but violence is probable, as in a “threat to the peace.” Thus conflict always involves a considerable degree of tension. The close relation of conflict to violence is indicated by the derivation of the term from the Latin word confligere, meaning “to strike together.” Thus, physical conflict is suggested.
