I would put miniature but that's just my opinion so don't take my word for it.
The United States gained control of the former Spanish colonies by going

For this question I would go on YouTube if you can and search The Great Dictator by Charlie Chaplin. It is a classic but it would help you so much with this report. Also the movie 'Unbroken' will help. If you need help message me because I had to do the same exact report when I was in 6th grade. Also here is a website from some of the soldiers experiences; http://www.military.com/Content/MoreContent?file=VSworld_war2
