I'm reading one now that was recommended to me by my Foreign Policy prof, but just as extracurricular, not as text. It's called
"Chinese Foreign Policy: Theory and Practice" by Thomas W. Robinson and David Shambaugh. I don't know if you're interested in world politics, but that one is really interesting. One we're reading along with the text in that class is
"Understanding International Conflicts: An Introduction to Theory and History" by Joseph S. Nye. It's alright. Another one about foreign policy is
"Hegemony or Survival: America's Quest for Global Dominance" by Noam Chomsky. I'm almost sure you'll like that one.
As far as U.S., we had to read one last quarter called
"Politics: Observations and Arguments, 1966-2004" by Hendrik Hertzberg. I also got one called
"The Almanac of American Politics, 2004" by Michael Barone and Richard E. Cohen, which is very informative. You might also like
"One Market Under God: Extreme Capitalism, Market Populism, and the End of Economic Democracy" by Thomas Frank. It's really blunt and to-the-point.
"The Sorrows of Empire: Militarism, Secrecy, and the End of the Republic" by Chalmers Johnson is also really interesting.
If you tell me what kind of books you want to read, my recommendations could be a lot better... just saying "political" books doesn't cut it. There are so many different ones out there. There are the Sean Hannity-esque analyses (from both sides), there are opinion-based books, there are historical books, etc. And there are so many subjects, too... are you more interested in U.S. politics, or abstract political thought, or the ideas, or what's actually going on, or the history of it, or foreign politics, or U.S. foreign policy... The list goes on.
Just make sure, above everything, that when you read these books, you take them with a grain of salt. Don't believe everything you read, even if the source is good. If you read about a conspiracy theory of some sort, don't just believe it's true; let it lead you to more books about that issue before you form an opinion. A lot of political books are out there just to convince you of something.
