Okay, so you know how we have to be careful and safe from bad things like germs and strangers? Well, countries also have to be careful and safe from bad things like people who want to hurt them or make them weaker. That's where the European Centre of Excellence for Countering Hybrid Threats comes in.
This Center is like a really smart group of grown-ups who work together to protect lots of different countries in Europe. They study and figure out ways to stop bad things from happening and help make sure that everyone is safe and strong. They do this by learning about all the different ways that bad people might try to hurt a country or mess with it, like using technology to spy or spread wrong information.
The grown-ups at this Center want to be really good at their job, so they share what they learn with other grown-ups who work to keep countries safe and help each other get even better. They also work with other countries that are outside of Europe to make sure that everyone is doing their part to be safe and strong.
In summary, the European Centre of Excellence for Countering Hybrid Threats is like a group of really smart grown-ups who work together to make sure that countries in Europe and around the world are safe and strong by stopping bad things from happening.
