Of the three theories, nuclear war is the least likely to occur using a liberal approach. Liberalism is an approach in which moral and political positions are based on the pursuit of liberty and equality for all before the law. Although there are many different branches and subsets of liberalism, the approach generally supports positions favorable to free markets, free speech, democracy, and equality for all. When it came to war, the early proponents of liberalism realized that war was costly. The gains from territorial expansion are not offset by the losses that citizens will suffer.

Get the original essay Liberalism calls for increased alliances and interdependence in the face of separatism. This is based on the knowledge that allies are less likely to go to war against each other. Additionally, economic interdependence is strongly correlated with whether a nation has an advanced economy. (Martin and Simmons, 1998). Normally, international organizations like the United Nations and the European Union seek ways to resolve disputes through discussion rather than through the use of some sort of military force. From a liberal perspective, these international organizations and institutions are of the utmost importance in achieving world peace. Liberalism is widely considered the main theoretical competitor to realism (Slobodchikoff, 2019). On the other hand, nuclear war under realism evolves from probable under offensive realism (projection) to possible for defensive realism (posture). Of the three theories, nuclear war is the most likely from a realism perspective. Realism is a school of thought in international relations theory, theoretically formalizing the Realpolitik statesmanship of modern Europe. Although a very diverse body of thought, it can be seen as unified by the belief that global politics is ultimately always and necessarily a field of conflict between power-seeking actors. It is important to note that realism is not a single theoretical perspective. Realism contains many different facets and approaches, many of which are still used today. Regardless of the approach taken, the central goal of realism is the pursuit of power, making it almost impossible to analyze the theory as a single coherent piece. A common misconception about realism is that all realists reject the role of ethics in international politics. For example, some classical realists believe that the national interest is of the utmost importance without rejecting the importance of moral judgment in international relations. The classical realist would instead place value on political actions taken, given the alternatives and likely consequences of those actions. There are also four traditional assumptions regarding realism. The first is that politics takes place between states, the latter being the main actors in international relations. Within a given state, there are bound to be multiple organizations, interest groups, and individuals, but from an international relations perspective, they are addressed by the state with which they are associated. The State will act as a unitary actor. This is especially true in times of international conflict, where states typically speak and act with one voice to show a united front. The second hypothesis is that most.
