Imagine if you were playing a game with your friends, and you all agreed to be nice to each other, share your toys, and play fairly. This is similar to the idea of idealism in international relations.
In international relations, countries try to work together to make the world a better place, just like when you and your friends work together to have a fun game. Countries try to make agreements and follow rules that are fair for everyone. They try to help each other when there are problems, like if there is a natural disaster or a war.
Idealism is the idea that countries can work together to make the world a better place, and that they should try to do what is right even if it is difficult. It is like when you decide to share your toys even if you really want to keep them all to yourself because you know it is the right thing to do.
However, like in playtime, not everyone always plays nice. There are some countries that try to cheat or take advantage of others. They might not want to follow the rules or share their toys. This can make it hard for idealism to work.
But just like how your parents might help you and your friends work out a problem, there are organizations, like the United Nations, that help countries work together and solve problems. They try to make the world a better place and encourage everyone to follow the rules.
Idealism is an important idea in international relations because it helps countries remember that it is important to work together and be fair. Just like how playing nice helps everyone have a fun and happy time, idealism helps countries have a better world for everyone.
