Hezbollah Movement in Iraq

Okay kiddo, let me try to explain this. Hezbollah is a group of people who live in a country called Lebanon. They believe in a particular religion called Shia Islam. Now, Iraq is another country that is nearby Lebanon. Some people from Hezbollah went to Iraq to help out some other people who also believed in Shia Islam. These people in Iraq were fighting against some other people who believed in a different kind of Islam. So, Hezbollah went to Iraq to help their friends fight against these other people. It's kind of like when your friend needs help with something and you go and help them. Does that make sense?
