Weapons can be good for their own safety at the same time, weapons can be a way to make money, by selling weapons. On the other hand, weapons can be a way to oppress people and protect their interests. The arms trade has been an important part of the Swedish economy. A significantly important thing that is increasingly normalized today is more arms exports to more countries This research problem I want to address is Sweden’s arms and munition exports to Saudi Arabia and the UAE between 2015 and 2020. It was in 2015 that Yemen war took place, and these countries chose to expand and strengthen their defense force to battle their enemies in the Yemen war. The purpose of this essay is how can Sweden’s weapons and munition exports to the United Arab Emirates and Saudi Arabia be explained based on realism and liberalism. Realism and liberalism are theories that can help me to examine and understand the subject I chose. The subject is very controversial because of the humanitarian situation in Yemen and very interesting to examine. The thesis' approach will be carried out based on qualitative methods where I will use content analysis. Qualitative methods mean that all material collected during the work leads to a desire to dig deeper to analyze. My approach will consist of mass media articles, internet slurs, and debate articles, these sources publish by magazines, collections, and other sources. As a result, Sweden has expanded its arms and munitions exports to Saudi Arabia and the UAE. The result of the study shows that realism characterizes the international scene and international relations.
