Which of the following is a threat to global security?

The correct answer is Terrorism.

To understand why this is the correct answer, let us analyze what constitutes a threat to global security and examine each option:
1. Terrorism: This refers to the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political, religious, or ideological aims. Because terrorist networks operate across borders, target innocent people globally, and destabilize governments, terrorism is universally recognized as a direct and major threat to global security.
2. Human Rights: The protection and promotion of human rights foster peace, justice, and stability. Promoting human rights is a means to build security, not a threat to it.
3. Arms Control: This involves international agreements to limit the development, production, stockpiling, proliferation, and usage of weapons. Arms control is a security-building measure designed to reduce the risk of conflict.
4. Disarmament: This is the act of reducing, limiting, or abolishing weapons (particularly weapons of mass destruction). Similar to arms control, disarmament is a policy aimed at preventing war and enhancing global safety rather than threatening it.

Therefore, among the given choices, only Terrorism represents a destabilizing force and a direct threat to global security.
