Foreign policy analysis (FPA) occupies a central place in the study of international relations. FPA has produced a substantial amount of scholarship dealing with subjects from the micro and geographically particular to the macro relationship of foreign policy to globalization. It brings together many different subject areas, indeed disciplines, as between international relations and comparative politics or political theory, or history and political science. FPA generates case studies of major world events, and the information that probes behind the surface of things, to make it more possible to hold politicians accountable. Meanwhile, officials themselves are ever more aware that they need assistance, conceptual and empirical, in making sense of how those in other countries conduct themselves and what can feasibly be achieved at the international level. However, each subject under FPA needs to be revitalized through the development of new lines of enquiry and through the struggle with difficult problems. Work is either already under way or should be pursued in eight important areas. These are (i) foreign policy as a site of agency, (ii) foreign policy and state-building, (iii) foreign policy and the domestic, (iv) foreign policy and identity, (v) foreign policy and multilateralism, (vi) foreign policy and power, (vii) foreign policy and transnationalism, and (viii) foreign policy and ethics.
Utilitarianism is inextricably linked to international ethics. The roots of the principle of utility can be traced to the 18th and 19th centuries, when it was employed by thinkers such as David Hume. However, Jeremy Bentham first formulated utilitarianism in detail and carefully studied its implications. According to Bentham, happiness is a condition in which an individual enjoys more pleasure than pain. Because utilitarianism is focused on the welfare of the individual, state boundaries are of little consequence. Its reach is inherently global. There are different varieties of utilitarianism. What sets them apart from other ethical theories is their stipulation that whatever is of value should be maximized for all and whatever of disvalue should be minimized for all. For Bentham, pleasure is the ultimate value. Later, John Stuart Mill distinguished between higher and lower pleasures and argued that higher pleasures should be given greater weight. In the 20th century, authors such as R. M. Hare determined that maximal satisfaction of preferences is the value to be sought. The utilitarian emphasis on maximization of value and its choice of values have generated much criticism from those who espoused human rights theories, such as John Rawls and those influenced by his work. At present, the scholarly literature dealing with issues related to international ethics mostly comes from those who are committed to human rights theory or who are committed to equality of outcomes for human beings.
