Common Security and Defence Policy

Common Security and Defence Policy (CSDP) is like a team of superheroes that work together to protect us all and make the world safer. CSDP is made up of all the countries in the European Union and they have come up with a bunch of ideas about how we can protect people and countries from bad things happening. They train people, share intelligence and technical know-how, and make sure everyone knows what the other countries are doing. CSDP also helps if there is a conflict and can even send people to help out in difficult situations. This all means that everyone is better protected and it's harder for bad things to happen.
