One book I can recommend is Saddam's Bombmaker: The Terrifying Inside Story of the Iraqi Nuclear and Biological Weapons Agenda by Khidr Abd Al-Abbas Hamzah, excellent, but scary book. "Hart's War" by John Katzenbach is another book I really liked. Anything by Stephen Ambrose is excellent. 'Ghost Soldiers': The Epic Account of World War II's Greatest Rescue Mission by Hampton Sides is a sobering account.
As far as fiction goes, any book by Frederick Forsyth is well worth the read. A particularly topical one (again) is The Fist of God by Forsyth, he wrote it after the Gulf War, but it is topical right now. I also tend to enjoy reading suspense novels, Jeffrey Deaver (The Bone Collector) is one I really enjoy. That's what I can remember off the top of my head. :)
