IntroductionIn our society, there are many systems that we can choose to follow, such as liberalism, realism and historical materialism. However, each of them has its dark sides and attractive parts. In my essay it is divided into three main parts. First of all, in each part, I will briefly introduce the basic concepts and in the following, I will analyze their disadvantages. Finally, I will discuss with you the interesting aspects of these three perspectives. Liberalism Liberalism as a political and moral philosophy focused on two major principles. These are individualism and freedom. First, liberalism places individuals at the heart of society. They believe that the greatest value of the social order is built around the individual. Secondly, the main goal of the company is to enable individuals to achieve their goals and realize their full potential if they choose to do so. Therefore, in this modern century, the majority of people prefer their states to act liberally, especially in the economic field. The concepts of liberalism have various advantages and disadvantages. On the other hand, liberals risk failing to tackle social problems. For example, as the global economy slows, weak government involvement risks increasing unemployment rates. Furthermore, the majority of people may enjoy the right to vote, but not all participants understand the issue they voted for. This is not fair to the rational decision maker. Furthermore, liberals are less concerned with distributional issues and less likely to reduce the wealth gap between strong and weak states. Furthermore, historical structuralists and realists judge that liberalism seems apathetic towards questions of the distribution of power. Powerful states get... middle of paper ...... natural gas and fossil fuels can be distributed to each state. Why are there still people suffering from hunger in Africa? This is an unequal distribution of resources in the world. If we apply historical materialism, supporting the redistribution of resources, each state can obtain a particular proportion of its resources. The world will definitely be much better and just.ConclusionAfter analyzing these three perspectives, I discovered that a new model could emerge if we mix these three ingredients and change it a little. Since they have their own advantages and disadvantages, if we take some useful elements such as the concepts of free market and rational thinking of policymakers, then we will get a new approach to international relations. I hope that after a decade we will emerge a whole new theory of international relations..
