⦁Can war economy policy influence peace and security? I believe war economics policy may contribute to international peace and security as positive impact more than negative impact. The reasons are as below: A first positive attitude behavioral possibility, any war economic policy can increase international interdependence through trade and finance raises the potential costs of war to a degree that makes welfare an irrational option of foreign policy can raise economic growth and builds good trading relationship between countries. Moreover, the use of superior economic and military power to harm an actual or potential aggressor's economy and make it stops preparing of waging war, e.g. US restricted Mexico imported to itself country, US invented military weapons to threaten to Korea to avoid nuclear war occurrence. In the past, US spent to military expenditure which could rise to employ soldier numbers to reduce unemployment as well as assisted military weapon manufacturers needed to employ many manufacturing workers to manufacture many military weapons for US government military fighting need.Hence, the relationship between war and economy will bring this basic question: Whether either can economics provide a growing tool for avoiding war or whether may consumption for resources and markets result in an increased likelihood of war? Following the increase of international trade and financial transfers in modern times. However, there has been a growing to concern the economic wisdom of war.Liberal economists oppose the idea that war might be a good business and advocated the promotion of peace and advocated the promotion of peace by international economic links among the different countries. Although, history has shown that enlightened economic self-interest was not always alike to contribute to the ultimate avoidance of war. But, a short overview of the liberal peace theory indicates, it takes a look at the amount ability of economic instruments as a means to enforce peace by an economically superior country or group of countries, e.g. within the framework of the United Nations or of regional organization for security and cooperation in Europe, the African Union or the organization of American States.
