Which of the following is NOT listed as a domestic national security threat?

• A. Climate change resilience
• B. Domestic terrorism/extremism
• C. Cyber threats to infrastructure/elections
• D. Border security/migration challenges

Answer: (A)

The main idea to grasp is what counts as a domestic national security threat versus a mitigation effort. The option describing climate change resilience focuses on preparing for and withstanding climate-related impacts. It’s about reducing vulnerability and maintaining essential functions, not about posing harm or a threat by itself. That makes it not a threat, but a capability or policy aim to lessen risk.

In contrast, domestic terrorism and extremism describe groups or ideologies that can actively threaten safety and stability. Cyber threats to infrastructure and elections target critical systems and processes, directly endangering security and governance. Border security and migration challenges involve pressures to the homeland’s sovereignty and safety, with real implications for security and resource allocation. These are recognized threats to domestic national security, whereas resilience is about countering those threats rather than being one.
