Although action by the United Nations has, at times, prevented or ended wars, reduced international conflict, and provided a forum for useful discussion of international issues by the world community, more effective global action against war could be secured by implementing a variety of measures.  These include setting limits on the veto in the UN Security Council, increasing the number of nations accepting the compulsory jurisdiction of the International Court of Justice, and securing wider ratification of the founding statute of the International Criminal Court.
