Which action is explicitly mentioned as part of North Korea's challenges to regional and global security?

• A. Nuclear weapons development
• B. Missile tests
• C. Military provocations
• D. Diplomatic negotiations

Answer: (A)

Nuclear weapons development is the action explicitly described as North Korea's challenge to regional and global security. This directly changes the strategic landscape by creating a credible nuclear deterrent and potential for nuclear use, which intensifies regional arms competition, heightens alliance tensions, and prompts international efforts on nonproliferation, sanctions, and diplomacy. While missile tests and military provocations contribute to increasing tensions, they are mechanisms that escalate the situation rather than the fundamental dimension of the threat. Diplomatic negotiations, on the other hand, represent a response strategy aimed at reducing risk, not the challenge itself.
