Polarity (international relations)Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes three types of systems: unipolarity, bipolarity, and multipolarity for three or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
Offensive realismOffensive realism is a structural theory in international relations that belongs to the neorealist school of thought and was put forward by the political scholar John Mearsheimer in response to defensive realism. Offensive realism holds that the anarchic nature of the international system is responsible for the promotion of aggressive state behavior in international politics. The theory fundamentally differs from defensive realism by depicting great powers as power-maximizing revisionists privileging buck-passing and self-promotion over balancing strategies in their consistent aim to dominate the international system.
State of natureIn Ethics and political philosophy, in social contract theory, religion, and international law, the term state of nature describes the hypothetical way of life that existed before people organised themselves into societies. Philosophers of the state of nature theory propose that there was a historical period before societies existed, and seek answers to the questions: What was life like before civil society?, How did government emerge from such a primitive start?, and What are the hypothetical reasons for entering a state of society by establishing a nation-state? In some versions of social contract theory, there are freedoms, but no rights in the state of nature; and, by way of the social contract, people create societal rights and obligations.
Collective securityCollective security can be understood as a security arrangement, political, regional, or global, in which each state in the system accepts that the security of one is the concern of all, and therefore commits to a collective response to threats to, and breaches of peace. Collective security is more ambitious than systems of alliance security or collective defense in that it seeks to encompass the totality of states within a region or indeed globally, and to address a wide range of possible threats.
Power (international relations)In international relations, power is defined in several different ways. Material definitions of state power emphasize economic and military power. Other definitions of power emphasize the ability to structure and constitute the nature of social relations between actors. Power is an attribute of particular actors in their interactions, as well as a social process that constitutes the social identities and capacities of actors. International relations scholars use the term polarity to describe the distribution of power in the international system.
Constructivism (international relations)In international relations (IR), constructivism is a social theory that asserts that significant aspects of international relations are shaped by ideational factors. The most important ideational factors are those that are collectively held; these collectively held beliefs construct the interests and identities of actors. In contrast to other prominent IR approaches and theories (such as realism and rational choice), constructivists see identities and interests of actors as socially constructed and changeable; identities are not static and cannot be exogenously assumed.
Liberal internationalismLiberal internationalism is a foreign policy doctrine that supports international institutions, open markets, cooperative security and liberal democracy. At its core, it holds that states should participate in international institutions that uphold rules-based norms, promote liberal democracy and facilitate cooperation on transnational problems (such as environmental problems, arms control and public health).
English school of international relations theoryThe English School of international relations theory (sometimes also referred to as liberal realism, the International Society school or the British institutionalists) maintains that there is a 'society of states' at the international level, despite the condition of anarchy (that is, the lack of a global ruler or world state). The English school stands for the conviction that ideas, rather than simply material capabilities, shape the conduct of international politics, and therefore deserve analysis and critique.
