So, in 1995, some countries in the world, including the United States, decided they needed to help people who were being hurt in a place called Bosnia and Herzegovina.
There were different groups of people living in Bosnia and Herzegovina and some of them didn't like each other very much. They were fighting and hurting each other and it made it hard for anyone to be safe or happy.
So, some countries decided to take action and help. They were part of an organization called NATO, which means North Atlantic Treaty Organization. This organization was made up of different countries that wanted to work together to make the world safer.
The countries in NATO decided to use their military forces to do something called bombing. That means they sent big airplanes with weapons on them to drop bombs on places where the fighting was happening.
The goal of all this bombing was to stop the bad people from hurting others. It wouldn't solve all the problems, but it could help to make things safer for the people who were being hurt.
The bombing went on for a little while and then the fighting slowed down. Eventually, people were able to start living more peacefully with each other. It wasn't perfect, but it was better than before.
In the end, the NATO bombing was a way for some countries to try and help other countries who were struggling. It was one way that people tried to make the world a better place for everyone.
