Why Do Nations Sign Treaties?

Imagine you and your friend both want to play on the swing set at the same time. You might make a secret handshake deal to take turns. In the big world, countries do this too. A treaty is like a super strong promise written down on paper.

If you just say "I promise," your friend might forget. But if you write it down, it is harder to cheat. Countries sign these papers so everyone knows the rules.

What if one country breaks the promise? Unlike kids on a playground, there is no giant referee for the whole world. So, treaties act like a rule book. They help countries solve fights without using fists.

A treaty is like a contract between friends, but for whole nations.

When countries sign, they agree to follow the rules. This keeps peace and helps them trade toys (or goods). It makes the world a safer, more predictable place for everyone.
