Treaties are important tools that help prevent conflicts between countries. They set up clear rules for how countries should work together and what each country is responsible for.

For example, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) was created to stop the spread of nuclear weapons. This treaty helps countries feel safer because it aims to keep dangerous weapons from getting into the wrong hands.

Treaties also help countries talk to each other and solve problems without fighting. The Paris Agreement on climate change is a great example. It brings countries together to promise to lower greenhouse gas emissions. This teamwork can help prevent conflicts that might happen because of environmental issues.

International organizations, like the United Nations (UN) and NATO, also play a big part in making treaties happen. These organizations help countries negotiate and make sure everyone follows the rules. For example, NATO has something called Article 5, which means if one member is attacked, all members will help defend it. This makes countries think twice before starting any aggression.

In short, treaties set the rules for countries to follow, encourage communication, and promote teamwork. This way, they help keep peace and reduce the chances of conflict around the world.
