Selected elements of global politics: Theoretical aspects, common threads, and empirical divergences in three "liberal" International Relations' approaches

i Abstract Liberalism encompasses many disciplines. Individual freedom, free-market capitalism, republican form of government, and rule of law are considered to be among its main pillars. The Thesis illustrates an original analysis of three partial "liberal" theories of International Relations (IR) - referred to as "approaches" because of their interdisciplinarity - and their main scholars' considerations vis-à-vis important selected elements of global politics, with peace as the general background. The three analyzed approaches are Economic Liberalism, Democratic Peace Theory, and Democratic Realism. Keeping into account their differences, traditions, and purposes, the approaches are operationalized through five subchapters - institutions, free-market, international law, conflict intervention, and nationalism - to prove their compatibility, non-contradiction, and possible juxtaposition vis-à-vis these features. Despite some "empirical differences", while looking at the selected-IR issues, the approaches have "common threads", and this is visible when the three frameworks and their top-selected scholars are confronted with the elements. After a general introduction on liberalism, a definition of peace in IR, and a quick overview of Peace Studies, the three approaches are presented in their theoretical..
