Hu Jintao, the current leader of the People's Republic of China, once said: “Diversity in the world is a fundamental characteristic of human society, and also the key condition for a vibrant and dynamic world as we see it today.” (Diversity Quotes) The people of the world have experienced war and peace between nations, but there is no specific theory as to why some countries always cause conflict. Fragmentation, global supply chains and other reasons have emerged in the analysis of wars, but the most precise and logical hypothesis is Thomas Friedman's Dell theory of conflict prevention. Thomas Friedman initially stated his theory that all countries that had a McDonald's fast food restaurant in would never go to war with each other. This theory has since been revised and is now considered “The Dell Theory of Conflict Prevention”. The Dell theory holds that as long as two countries are each a segment of a global supply chain, they will never go to war with each other (Friedman). For example, any country that sells, produces, trades, etc. Dell Computers will never go to war with another country that does the same. This theory, however, fits any global supply chain, not specifically Dell computers. Friedman believes that this theory is the reason why some countries have never declared war on other countries because of the similarities they possess. The responsibility that the country has in the global supply chain puts other components in danger if it were to go to war with someone who is also involved in the chain. Samuel P.
