Overblown: How Politicians and the Terrorism Industry Inflate National Security Threats, and Why We Believe Them is a book by the American political scientist John E. Mueller published in 2006.
Mueller, an expert on war and terrorism, had been expressing critical views of the terrorism industry for some time before publishing this book.
Mueller's central argument is that an American is more likely to die of drowning in the bath than in a terrorist attack, and that the rational response to terrorism is to keep the threat in realistic context, and otherwise getting on with life.
That this does not happen has something to do with the terrorism industry--experts, journalists and politicians—and something to do with the human inability to assess risk and chance accurately.
Mueller goes in his book to extend his central argument to other varieties of national security threat.
