Okay, kiddo, let me explain what happens when the United States goes to other countries to get involved in their problems.
So, you know how sometimes your little sibling might take your toys without asking, and you need to step in and solve the problem? Well, that's kind of what the United States does, but instead of toys, it's bigger problems like war, terrorism, or human rights violations.
Sometimes, other countries might be having trouble getting along with each other or there might be a bad ruler who treats their people badly. The United States might decide to help solve these problems by sending in their military or talking to the leaders to try and come up with a solution.
But, just like how you wouldn't want someone coming in and taking all of your toys without asking, some people in other countries might not want the United States getting involved. They might feel like it's none of their business or they might be upset that the United States is trying to tell them what to do.
It's important for the United States to be careful when they are getting involved in other countries, and to make sure they are doing it for the right reasons. Just like how you need to be careful when solving problems with your friends and family.
Does that makes sense, little one?
