Okay kiddo, let me explain National Liberation Army (NLA) in Bolivia to you in a way that you will understand.
First, let's start with the country Bolivia. It is a place where people live, like your city or town. Bolivia has its own government that makes rules and decisions about what people can do and what they can't do.
Now, sometimes people in Bolivia don't like the decisions made by their government. They may feel like they are being treated unfairly or not getting what they need. When a lot of people feel this way, they may come together to protest or fight against the government. This is what happened with the National Liberation Army (NLA).
The NLA was a group of people in Bolivia who wanted to change the government because they thought it was not treating the people of Bolivia fairly. They wanted to create a new government that would listen to the needs of the people and work to make their lives better.
However, the government of Bolivia did not like this and thought that the NLA was trying to harm the country. So, there was a lot of fighting between the NLA and the government, where people were hurt and some even died.
Eventually, the NLA was defeated by the government, and they stopped fighting. But their ideas of wanting a fair government that listens to the people stayed. Even today, many people in Bolivia still want this change, and they work to make their voices heard so that their government can do better for them.
So, to sum it up, the National Liberation Army (NLA) was a group of people in Bolivia who wanted a fairer government for their people. They fought against the government, but were eventually defeated. Their ideas, however, still inspire people to fight for a better government today.
