ABD'nin Afganistan politikası, 2001-2021: Askeri müdahaleden askeri geri çekilmeye

The 9/11 terrorist attacks that took place at the beginning of the 21st century were among the most critical events that has shaped the century. With concretization of the concept of international terrorism, it has entered the agenda of states as one of the biggest threat and security problem of the new era. The US as the victim of the attacks was most affected. While the attacks caused a foreign policy change for the US, the term "global war on terror" emerged and led to US military intervention in Afghanistan, which would last for about 20 years. With the beginning of the Afghanistan intervention, very different discussions started in the literature. It has become important to evaluate this intervention in terms of both US foreign policy and the concept of humanitarian military intervention. The questions that constitute the main subject of this thesis are shaped by these two evaluation points. Was US military intervention in Afghanistan morally legal and necessary? Was US military intervention in Afghanistan necessary for US interests and foreign policy? If there is no necessity from both perspectives, what is the logic behind US intervention, the reason for continuing of intervention and the reason for complete withdrawal after almost 20 years? In order to answer these questions, the thesis evaluates the necessity of humanitarian intervention through the theory of "just war", and from a realistic point of view. From these two perspectives, an assessment is presented by explaining the reasons behind the US decision of withdrawal. The reasons for the prolongation of the intervention process, which could not be considered as successful from both respects, are also examined.
