Peace and development are two main themes of the world today,but we still have rigional conflicts or even local wars in the middle east or places alike.

Comparing with prosperity and peace, war and death would be last choices for human beings,but why people choose to behave so radical and cruel, I think there are many factors acount for this:

power politics and hegemony pactising by major countries like the U.S.

religious and belief difference of people.

the ever growing gap between the western countries and their counterparts.

maintain peace of the world is by no means an easy task at all, it entails combined efforts from all walks of life,narrow the gap between developed nations and the poor ones politically and economically,bring international roles of organizations like the UN and WTO into full play thus stop war at the first sight.

Globalization is progressing with each passing day and we have already in the bracement of the new centry, we are and we should be confident that we can stop the evil spirit of war by jointed efforts.
