What can the president or SecDef do if deterrence operations to stop proliferation are not successful?

• A. Launch a diplomatic initiative.
• B. Pursue economic sanctions.
• C. Authorize unilateral disarmament.
• D. May direct the joint force commander to employ or support WMD counterforce operations.

Answer: (D)

Deterrence failing means a direct, military course of action becomes necessary. The president or Secretary of Defense has the authority to direct the joint force commander to employ or support WMD counterforce operations. This option provides a way to degrade or neutralize an adversary’s weapons and delivery systems, aligning with civilian oversight and the legal framework for using force. While diplomatic efforts and economic sanctions continue to be part of the broader strategy, the military option described is the mechanism for taking decisive action when deterrence does not succeed.
