The diploma thesis analyzes the impacts of maritime piracy on international community. The study analyzes the situation in terms of economic impacts, but also in terms of international cooperation in solving piracy issues. The aim of the diploma thesis is to define most vulnerable locations, quantify economic impacts and evaluate the impacts of military missions in the affected regions, as well as analyze the published recommendations.

Indiana University-Purdue University Indianapolis (IUPUI) / The global climate is creating more ice-free waters in the Arctic. These new navigation possibilities around the Arctic lead to increased global trade, tourism, and oil and gas exploration. With the foreseeable increased nautical transportation through the Northwest Passage, the United States needs to revisit its security posture in and around the Bering Strait. At least five different grand strategies are potentially relevant in addressing this question. By comparing the suggestions of these leading grand strategy approaches to what has actually been implemented by the United States in the Strait of Hormuz, the Strait of Malacca, and the Panama Canal, similarities emerge that can help the United States shape their strategy for the defending of its national interests in the Bering Strait. By testing the different grand strategies against three reasonably similar cases, I find that a forward military presence and supporting a liberal institutionalist approach are the two key aspects that the United States should employ in the Bering Strait. Increasing and improving the military presence that the United States has in the region should be a top priority. In addition, supporting the Arctic Council would provide an increased level of security to the United States and other nations in the region. This strategy is not without its challenges and it will require artful statecraft in order to be successful.

This dissertation explores the growing field of study around Maritime Security. While an increasingly common sub-heading in American naval strategy documents, maritime security operations are largely framed around individual threats (i.e. counter-piracy, counter-terrorism, counter-narcotics). Here, we endeavor to explore how a seemingly disparate set of transnational issues fit into a more coherent framework to give greater theoretical substance to the notion of Maritime Security as a distinct concept. In particular, we examine, as our research question, whether the Broken Windows theory, a criminological construct of social disorganization, provides the lens through which to theorize maritime security in the littorals. By extrapolating from criminology, this dissertation engages with a small but growing impulse in studies on insurgencies, terrorism, and piracy to look beyond classic theories of security to better understand phenomena of political violence. To evaluate our research question, we begin by identifying two critical components of the Broken Windows theory, multidimensionality and context specificity. Multidimensionality refers to the web of interrelated individuals, organizations, and infrastructure upon which crime operates. Context specificity refers to the powerful influence of an individual or community's environment on behavior. These two themes, as explored in this dissertation, are brought into stark relief through an application of the Broken Windows theory. Leveraging this understanding of the theory, we explore our research question by employing process-tracing and detailed descriptions across three case studies (one primary and two illustrative)—the Caribbean Basin, the Gulf of Guinea, and the Straits of Malacca and Singapore. In so doing, we demonstrate how applying the lens that Broken Windows provides yields new and interesting perspectives on maritime security. As a consequence, this dissertation offers an example of a theoretical framework that provides greater continuity to the missions or threats frequently binned under the heading of maritime security, but infrequently associated with one another in the literature.
