Exportive engineered migration, and its increased use in recent years, have progressively gained salience in European politics. The countries targeted by exportive engineered migration have taken exceptional and securitized measures to respond to its use, derogating from the international asylum regime and its core norms and values. Yet, despite its growing salience, how the use of exportive engineered migration against a liberal democracy influences the target state’s internal political dynamics and adherence to liberal norms remains poorly understood. This thesis explores how migration was securitized in Finland following Russia’s use of exportive engineered migration at its eastern border in the fall and winter of 2023. Using securitization theory, and focusing on public television appearances and parliamentary discussions of Finnish MPs during and in the aftermath of the border crisis, the discourse-historical analysis delves into the particular argumentative strategies used in the securitization process. The thesis concludes that the way in which engineered migration was securitized helped to create a discursive environment and perceived political reality, which made derogations from the international asylum regime commonsensical and a necessity to ensure Finland’s national security and sovereignty.
