Which combination of actions has the US and its allies used to deter North Korea's military advancements?

• A. Economic sanctions, diplomatic negotiations, and military preparedness
• B. Cultural exchanges and tourism
• C. Unilateral troop withdrawal
• D. Food aid and humanitarian programs

Answer: (A)

Deterrence in this context hinges on presenting a credible mix of costs and channels that make pursuing military advancements unattractive. Economic sanctions raise the price for continuing or expanding weapons programs, diplomatic negotiations keep open avenues to limit and monitor those programs while offering concessions for restraint, and military preparedness signals that the United States and its allies are ready and able to respond if red lines are crossed. The combination of squeezing economic incentives, maintaining diplomatic pressure, and demonstrating military readiness creates a layered and credible threat of consequences, which is why this approach is the most effective way to deter North Korea’s advancements.

Soft power tools like cultural exchanges and tourism don’t directly deter military programs. Unilateral troop withdrawal would weaken the deterrent signal. Food aid and humanitarian programs address humanitarian needs but don’t decisively address security concerns or the incentives behind military development.
