Sapo, Sweden's security service, warns that Russia poses the greatest threat to Sweden due to its aggressive stance towards the West. While Sweden's NATO membership has bolstered security, it has also led to increased Russian intelligence activities. The report highlights serious security concerns, including hybrid warfare and violent extremism. Sapo's head, Charlotte von Essen, emphasizes the need for vigilance against destabilizing narratives. The report also identifies Iran and China as significant threats, with terrorism remaining a high concern.
