In counterinsurgency operations during the Vietnam War, what is considered the center of gravity?

• A. The will of the enemy
• B. The people
• C. The political leadership
• D. The army

Answer: (B)

In counterinsurgency, the lasting power of an insurgency rests with the support of the local population. The people provide the lifeblood of operations—intelligence, safe havens, recruits, and legitimacy. In the Vietnam War context, winning the trust and protection of civilians reduced the insurgents’ sanctuary and supply lines, while bolstering the government’s authority and ability to govern. When the population is aligned with the counterinsurgency effort and perceives security and legitimacy from the government, the insurgency loses its base and the ability to sustain itself.

The army and political leadership matter, but their effectiveness hinges on popular backing. Without the people’s support, military force alone struggles to compel a long-term victory, because insurgents can blend back into civilian life and continue to operate. The will of the enemy is a factor, but the practical driver of an insurgency’s endurance is the population’s loyalty and cooperation.
