Can total peace be someday achieved on earth? Why do I use the word TOTAL when talking about peace? Wikipedia defines Peace as "Peace is a state of harmony characterized by the lack of violent conflict and the freedom from fear of violence. Commonly understood as the absence of hostility, peace also suggests the existence of healthy or newly healed interpersonal or international relationships, prosperity in matters of social or economic welfare, the establishment of equality, and a working political order that serves the true interests of all. In international relations, peacetime is not only the absence of war or violent conflict, but also the presence of positive and respectful cultural and economic relationships.", as published by Shirin Ebadi in her book THE MEANING OF PEACE, she defines peace as "Peace means serenity. One can only feel serene if one's human rights are not violated and one's integrity is protected. Obviously a human being who does not have access to education due to extreme poverty, or who has been sentenced to imprisonment for expressing his/her opinion does not enjoy serenity and does not live in peace. The same is true of a person who has lost his/her home and lives on the streets." Now looking at both definitions, we are tempted to conclude that PEACE equals,

1- Social equality

2 - Economic stability

3 - Conduicive physical environment

The United Nations Development Programme defines development as 'to lead long and healthy lives, to be knowledgeable, to have access to the resources needed for a decent standard of living and to be able to participate in the life of the community .'Looking at what we mean by sustainable development today and as defined by the UNCSD - ""development which meets the needs of current generations without compromising the ability of future generations to meet their own needs" we realize that the needs referred to here are Social, Economic and Environmental. 

Therefore, after personal analysis and comparison I conclude that GLOBAL PEACE = GLOBAL DEVELOPMENT. Thus, if we strive to live in a world of peace, we will be striving towards attaining the development we want to see in the world and the same goes for sustainable peace and sustainable development.
