Okay kiddo, let's talk about some really big and scary things – war and genocide.
War is like a big fight between two or more groups of people, countries or communities. It can start because they disagree on something and can't find a way to solve it without fighting. Sometimes war starts because one group wants something that the other group has, such as land or resources. When people go to war, they use weapons like guns, bombs, and other things that can harm people and destroy buildings and homes.
Now, genocide is even scarier. It means that one group of people, like a race or a religion, wants to get rid of another group of people completely. This is wrong, and no one should ever want to do this to another group of people. It's like a really mean and horrible bully who wants to hurt another kid just because they are different.
The person who does this horrible thing is called a genocidal leader, and they might try to kill people, destroy their homes or take away their food and water. This can cause a lot of suffering, and some people might have to leave their homes and become refugees, which means they have to find somewhere else to live because it's not safe for them to stay where they are.
When people talk about the terrible things that happen in war, they might also talk about the things that happen after the war, like when one group of people might be punished because they lost the war. This is called war crimes and it’s when soldiers or leaders break the rules of war and hurt innocent people.
In short, war and genocide are really bad things that should never happen. It's always important to remember that every person has value and that we should always treat others with kindness and respect, even when we disagree with them.
