The only way to create a peaceful world is for nations globally to interact with eachother and work together. there are many ways of doing this. for example events such as the olympics promote a good atmosphere that enhances relations. to achieve world peace though we must go alot further. the sort of thing that is necissary is a remake of the league of nations. i believe it would stand alot better chance of success today than it did after a major world war as doubts would not be so high and people are not so hostile against eachother. it is becoming increasingly accepted that people are all equal, and although i am not naive enough to believe this is the case all over the world, i believe that now would be as good a time as any in the near future to try as things are beginning to settle down in the middle east (although they are obviously not resolved). we also need the new league to have better organisation than it did the last time round with only a majority vote of say more than 75% needed to take an action instead of everyone needing to vote the same way. also i believe relations are now strong enough in europe and america that the league would have enough backing to succeed, (unlike last time).
