Which strategy is NOT effective in counter-insurgency operations?

Decreasing engagement with local communities is a strategy that is not effective in counter-insurgency operations because successful counter-insurgency heavily relies on the support and trust of the local population. Engaging with communities helps in gathering vital intelligence, understanding local issues, and winning hearts and minds, which are crucial in undermining insurgent influence.

In contrast, building rapport with local leaders, using information to inform tactical decisions, and adapting operations based on real-time intelligence all contribute positively to counter-insurgency efforts. These strategies foster cooperation, ensure informed decision-making, and enhance responsiveness to dynamic situations, thereby creating a more conducive environment for stability and security.
