As for the general philosophical views, it is excellent and still applicable today... especially to your situation. A few quotes from the book can be found here. One way or another, the book is considered a classic in the West.
The following works also get my recommendation:
The Second Treatise of Civil Government by John Locke
The Wealth of Nations by Adam Smith
On Liberty by John Stuart Mill
You may notice that none of the authors I recommended are American; two are English and one is Scottish. Nevertheless, their views on the function of government, the proper management of an economy, and the importance of human liberty heavily influence American thinking, and I hope that they will inspire you and your fellow students in your noble endeavor.
I need to go to sleep now (it's 1:00 AM where I am), but I'll leave you with this:
"Liberty is not a means to a higher political end. It is the highest political end." --Lord Acton
By the way, if you ever travel to the United States, let us know. We'll show you around.
Good Night!
John Locke is my hero too! :-P
Thanks for the offer but I think I will travel to the US as a citizen of free Iran, not the one that supports terrorism and takes Americans hostage!
