Okay kiddo, let's talk about the strategic hamlet program. During a war a while back, the government wanted to protect their people from the enemy, who weren't happy with the government. So they made a plan to put people who were on their side in little places called hamlets, and they would protect those hamlets with little walls and fences. They wanted to keep the enemy out and the people who were on their side safe.
Now, some people who had been living in the area for a long time didn't like that plan. They didn't want to live in the hamlets because they felt like it was taking away their freedom. They wanted to live the way they had always lived, and be in charge of their own homes and land. The government didn't like that, and sometimes they forced these people to move into the hamlets anyway.
In the end, the plan didn't work too well. The enemy found ways to get into the hamlets and sometimes the people on the government's side didn't want to stay in the hamlets, so the plan didn't always protect them. After a while, the government stopped trying to make everyone live in the hamlets and came up with other ways to protect people.
