Security Dilemma
/sɪˈkjʊərəti dɪˈlɛmə/
Key Insights
According to the Security Dilemma, if one state increases its security capabilities, this simulataneously reduces the security of another. Consequently, security-increasing measures lead to a cycle of increased tensions, escalations, or conflicts. This occurs because it is hard to know about other states' intentions: Do they simple gear up their defence capabilities or are they actively preparing for war? Hence, efforts to enhance security can lead to greater instability due to the misperception of intentions and the lack of trust in the international system.
