Which concept describes the protection of a country from external threats and maintaining sovereignty?

• A. National security
• B. Global communication
• C. NAFTA
• D. SDI

Answer: (A)

National security is the idea of protecting a country from external threats and preserving its sovereignty. It involves guarding borders, deterring aggression, maintaining military readiness, and safeguarding critical infrastructure and citizens from war, terrorism, cyber attacks, and economic pressures. By strengthening national security, a nation helps preserve its political independence and control over its affairs, which is the essence of sovereignty. The other terms describe related but narrower ideas: global communication is about exchanging information globally, NAFTA is a trade agreement, and the Strategic Defense Initiative was a specific defense program rather than the broad concept of safeguarding a nation.
