For some the title is the necessary cause and purpose or usefulness of war. For this we must relevate our Fundamental Formalization of “An Inquiry into the Nature and Causes of the Wealth of Nations. We also must be allowed to think implicately lest we are unable to truly understand what it means to point out as the “Cause of War”. Since great nation have shown to arise from an equilibrium of the 4 basic needs/wants, then it is necessarily the shifting of these resources and in relation to the powers or nations that controls them that is responsible for conflict, or the destruction of that which could be trade for more efficiency in mutually beneficial barter.
Admittedly looking at today economy and geopolitical climate the needs and wants of each region or nation are far more complex than the basic 4 outlined by the author, however by having a deep understanding of the fundamentals of what creates great nations we might understand the important factors in creating mutually beneficial stable equilibrium.
If a nation is starving for example, it might be compelled or forced to go to war in order to attempt to feed itself. The same could be said for a nation that sinks under its own waters and needs new land to re establish order. The great obstacle of peace then is to decentralize and stabilize these 4 resources in relation to every region habitated by mankind.
When we see conflict between nations we should look to alleviate one of these 4 pains.
It could be said just as easy that war is the machine that plows ahead until the next great equilibrium is found.
Extending 4,000 miles (6,437 kilometres), the Silk Road derives its name from the lucrative trade in Chinese silk carried out along its length, beginning during the Han dynasty (206 BC – 220 AD). The Central Asian sections of the trade routes were expanded around 114 BC by the Han dynasty, largely through the missions and explorations of Chinese imperial envoy, Zhang Qian. The Chinese took great interest in the safety of their trade products and extended the Great Wall of China to ensure the protection of the trade route.
Trade on the Silk Road was a significant factor in the development of the civilizations of China, the Indian subcontinent, Persia, Europe, and Arabia, opening long-distance, political and economic interactions between the civilizations. Though silk was certainly the major trade item from China, many other goods were traded, and religions, syncretic philosophies, and various technologies, as well as diseases, also travelled along the Silk Routes. In addition to economic trade, the Silk Road served as a means of carrying out cultural trade among the civilizations along its network.
Further expansion of the Islamic Turks in Central Asia from the 10th century finished disrupting trade in that part of the world, and Buddhism almost disappeared.~http://en.wikipedia.org/wiki/Silk_Road
