IntroductionTen years ago, the German government decided to engage in the "war on terrorism" and its Operation Enduring Freedom (OEF) and to intervene in Afghanistan as part of the International Security Assistance Force (ISAF). This decision is based on United Nations Security Council resolutions 1368, 1378, 1383 and 1386 of November and December 2001. These resolutions legitimize the general conditions of the intervention from the point of view of international law. Therefore, Germany's participation in the war within the framework of the mutual collective security system also referred to Article 24 of the German Basic Law (2006, p. 22). But why did the German government vote to deploy military forces in Afghanistan? The initiative for the intervention came from the United States as a reaction to the terrorist attacks of September 2001 to ensure the status of a hegemonic power (Buro, 2009, p. 10). But civil war and terrorist networks were by no means a new phenomenon in Afghanistan. The German motivations that led to the decision to join the OEF and ISAF are the main research topics of this article. It also intends to analyze the decision-making process relating to Germany's participation in the war according to the methodological approach of 'Bureaucratic Politics', explained by Graham Allison (2008). To ensure a solid understanding of this complex process, this article will analyze all three models of Allison's approach. It seems necessary in relation to the German political system, in which organizations as well as individuals are closely linked as an essential part of politics and therefore influential actors in government decision-making. In this context numerous......middle of paper......advantage for Germany after the war and the establishment of a liberal economic system, Western democratic values ​​and institutions. It would be the best way to promote peace and foster prosperity, both for Afghanistan and for the entire world. Furthermore, neoliberalism assumes that democracies do not fight each other. The German government supports these goals and a “state-building process” in its “Afghan concept,” which defines the interdependence between security, development and reconstruction (2007, p. 15-30). Furthermore, the importance of non-state institutions and services actors that neoliberalism attributes to international politics such as human rights, environmental issues as well as threats from terrorist organizations and networks create an explanatory power of the global system that is completely missing in the theoretical approach of neorealism.
