wants

Joe wants to be a freak-show person in the circus, which will help him get out of the hospital. He also wants to get out of the hospital because he wants to go home. Therefore, working as a freak-show person will allow him to make, which, he thinks, will ultimately allow him to go back to America. However, it is not easy for him to go back to America because people tell him that it is against regulations. (But, really there aren’t regulations; people are just telling him that there are so he would give up.) It is “against regulations” because the people in power don’t want civilians to see what war can do to people. They don’t want to impose negative views on war, because they think the military would collapse.
