Since the Hamas attack, 7 of October 2023, instability in the Red Sea region has occurred. Due to this, the United States, along with other western countries has made a military intervention to targets in Yemen. But the question remains, how has it been possible for the US to carry out a military attack? This paper is aiming to study how the US has made this intervention possible by analyzing the securitization of the threat image from the Red Sea region. The study is going to analyze the ATA (Annual threat Assessment) material from the years 2006-2024, the report shows next year's US threat image. By the Securitization Theory the study is aiming to see how the threat image has been securitized. Combined with a discourse analysis as a method the study will investigate how the Red Sea region is expressed in the reports. This material, theory and method have not been studied before and therefore filled a gap in the previous research field.  The purpose is to contribute to a wider picture of the Securitization theory in the international arena. The analysis shows that ATA reports contain clear signs of securitization. The results show that the reports contained loaded words, an authority that was targeting an audience and macro securitization had occurred by mentioning the conflict in the Red Sea region as a proxy war. Due to these results one could draw the conclusion that Securitization had occurred in the report and therefore made possible for the military invasion.
