Introduction Libertarianism is a philosophy that embraces freedoms in the choices and pursuance of issues in all the realms of society. Within the philosophy of libertarianism lies the question of moral responsibility and moral justice for the actions of individuals or states when looked at from a broader perspective. One of the areas where this philosophy has been applied in the field of politics, especially the area of foreign policy. Proponents of libertarianism also referred to as libertarians, argue for the free will of states when it comes to the development of policies that guide their interaction with other states. This paper presents a supportive argument of the philosophy of libertarianism, especially its application to the field of foreign policy. The paper argues that the libertarians present a desirable framework on which the foreign policy grounds are supposed to be established in international relations. Overview of libertarianism and foreign policy As observed in the introductory part of this paper, libertarianism is a political philosophy that puts liberty at the center of interaction in all the realms of interactions between states on the global scene. Liberty, as used in the postulation of the arguments in the libertarian school of thought in the field of political science, means action based on the free will. It also means that individual actors do not have to be interfered or forced to align with a certain cause that they deem unfavorable or unfit for their choices. Libertarianism, as applied in the foreign policymaking process, is based on the assumption that individual countries have a right to do whatever they want as long as their decisions and practices do not infringe on the rights of other states (Buley 222). According to Duncan and Machan (3), libertarianism is the basis on which the principles of liberalism in the contemporary global political economy are rooted. Libertarianism is widely referred to as classical liberalism. Thus it argues for the openness in conducting affairs for the sake of the collective benefits of actors and those who are affected by the actions. Opinions and theses by libertarians on foreign policy One of the arguments that are inherent in the opinions that are raised by the supporters of libertarianism about foreign policy is that states take protectionism approaches when it comes to the development of decisions that guide their interactions with other states in the world. The central issue that comes out when it comes to foreign policy choices by states is the issue of national security and the role of the government in safeguarding the rights and freedoms of the citizenry. However, it is important to observe that libertarianism reiterates the observance of the principle of mutual respect, even as states seek to attain their national goals in international relations. Whether this can be attained is an issue that is debatable. Nonetheless, the most critical thing is that libertarianism provides a framework that guides the cooperation of states when it comes to the development of relations and the enhancement of objectives (Huebert 190). Huebert (190) observes that the proponents of libertarianism support the principle
