Okay kiddo, so you know how sometimes you have friends who come over to play, and you all agree on some rules so that everyone can have fun and play together, right? That's kind of what the NATO Summit is.
NATO stands for North Atlantic Treaty Organization, and it's a group of countries that have agreed to work together to keep each other safe. They all have each other's backs, like good friends do.
So every once in a while, the leaders of all these countries get together to talk about what's been happening in the world and how they can help each other. That gathering is called the NATO Summit.
During the NATO Summit, the leaders talk about things like how to make sure everyone has enough money to keep their military strong, and how to work together to stop bad guys from doing bad things. They also talk about ways to help each other out when there are natural disasters, like earthquakes or hurricanes.
It's a really important meeting because it helps all these countries keep working together and supporting each other, just like good friends do.
