ELI5: Explain Like I'm 5

Crime of aggression

Crime of aggression is when someone, like a country or group of people, decides to attack another country without a good reason. Imagine it's like when two kids get into a fight over a toy even though one of them did not do anything wrong to the other.

To stop this from happening, there are rules set up by countries all over the world that say countries can't just attack each other for no good reason. These rules are kind of like having a teacher on the playground who makes sure all the kids play fair and don't hurt each other.

If a country or group of people breaks these rules and starts an attack without a good reason, they could be in trouble with other countries who are trying to play by the rules. Think of it like getting in trouble with the teacher for breaking the rules on the playground.

So, to sum up, crime of aggression is like when someone starts a fight without a good reason, and there are rules in place to stop this from happening because it's not fair and can hurt people.
