What is the difference between nonproliferation and counterproliferation?

• A. Nonproliferation is for preventing proliferation; Counterproliferation is for defeating the threat.
• B. Nonproliferation and counterproliferation are the same.
• C. Nonproliferation aims to use diplomacy; Counterproliferation uses force against states.
• D. Nonproliferation targets individuals; Counterproliferation targets states.

Answer: (A)

Prevention versus active defeat. Nonproliferation aims to stop the spread of weapons, materials, and know-how before they can be used, achieved through diplomacy, international treaties, export controls, verification, and peaceful measures. Counterproliferation focuses on neutralizing a threat that is already emerging or underway, using actions designed to defeat, deter, or disrupt proliferator capabilities—often involving interdiction, disruption of supply networks, and other targeted measures, including force if necessary. That’s why preventing proliferation through agreements and oversight is distinct from taking up arms or other strong actions to stop a proliferator’s program in real time. The other choices mix up or narrow these ideas: they aren’t the same, and they don’t capture the prevention-versus-active-defeat distinction, nor do they accurately describe the typical targets and tools of each approach.
