Ok, so imagine you and your friend are playing with blocks. You both have different ideas on how to build something, but instead of talking it out and working together, you start saying mean things about each other's ideas to get your friend to stop building their thing and do what you want.
Well, something like that happened between Russia and Ukraine. Ukraine wanted to do things their own way and make their own decisions, but Russia didn't like that. Instead of having a nice conversation and finding a compromise, Russia decided to spread false information to make Ukraine look bad and confuse people.
You know how sometimes grown-ups tell you things that aren't true? Well, Russia did the same thing. They started making up stories and spreading them around to make Ukraine look like the bad guy. They wanted to make it seem like Ukraine was treating people badly and causing problems. This made it harder for people to support Ukraine and made it easier for Russia to do what they wanted.
Russia used different tactics to spread this disinformation. They used social media, TV, and websites to share fake news stories that made Ukraine look bad. They even created fake accounts and pretended to be real people spreading these lies. They did this to try and control what people thought and believed about Ukraine.
It's like if you were playing a game with your friends, and one friend kept making up rules and telling everyone that they were the only ones who knew the right way to play. People might start believing them and following their made-up rules, even though they might not be fair or true. That's what Russia did to Ukraine.
This disinformation made things really confusing and difficult for people in both countries. It made it harder for them to trust each other and find a peaceful solution. It's important to always question information and think for yourself, especially when people are spreading rumors and telling you things that don't quite make sense.
In the end, it's important for countries and people to have honest conversations and work together to solve problems, just like you and your friend should talk and find a way to build something together.
