is the US in Iraq?

Why is the US in Iraq? Do we have to clean up every ones messes? Everyone puts us down but if we were not here to do it then no one else would. How about we sit back and let the world crumble and do nothing about it and see how everyone comes crying to us to help them. We go and clean up other countries when our own has starving women and children and veterans who fought to keep us safe living on the streets. It is a good thing we take care of things the way we do. But things need to be taken care of here also...
