In the context of an emerging multipolar world, the transatlantic partnership faces variouschallenges in the attempt to maintain the Western-shaped and dominated liberal order. This article aims tosynthesize and rationalize the central argumentative positions on the ever-evolving transatlantic relationshipprovided by the following theories of international relations: neorealism, neoliberalism and constructivism.A combination of the main assumptions of the three approaches brings useful insights into the policy debateson the role of the transatlantic partnership in the process of forging the global governance. Nevertheless,where the systemic theories such as neorealism and neoliberalism fall short in explaining the transatlanticrelations, constructivism, with its focus on actor identity succeeds in offering a dynamic account of them.
