Final answer:
International anarchy is a condition of no central global authority, leading states to prioritize their own interests and security, which in turn contributes to the security dilemma where self-defensive measures by one state can provoke others.
Step-by-step explanation:
International anarchy refers to the condition within the international system where there is no overarching governing authority, leading to a lack of a general sense of order as sovereign states pursue their own interests. This state of affairs relates to the security dilemma in that each state, in the absence of a centralized enforcement mechanism, may seek to enhance its own security but, in doing so, unintentionally threatens other states, which could lead to increased tensions or conflict as each state strives to protect its sovereignty.
