This chapter deals with international trade and globalization as the spearhead of thematic parts of the textbook. In this book, the causes of World War II were seen as the recognition of disparities and the accumulation of discontent among the least developed countries, especially the collapse of the bloc economy, or free trade. However, it has not discussed why the closure of countries in trade could be a major international problem. How a free trade regime can be good for the world and how it can be maintained must be theoretically examined and discussed. It is with these issues in mind that we proceed in this chapter.
