Personally, I know nothing about the political theories. I am a kid who likes to learn, but I gotta tell ya, my interest wasn't piqued with that brief introduction. I can see where you would want to double dip, but the subject seems like it wouldn't really fit the speech assignment.
Terrorism, on the other hand, could potentially be a very interesting topic. History is my favorite subject. The American Revolutionaries used means that could be defined as terrorist tactics. If you do tackle the subject of terrorism, I would avoid talking just about terrorism directed at the United States and its allies today, but terrorism in a more general sense. You might even want to leave people thinking of terrorism as something that is not black and white. Or ... guerrilla warfare could be another interesting topic. See how I am? I spit out things that would be interesting to ME. Do keep in mind your audience when you are deciding on a subject though.
