The book tells readers that to waste gasoline (read oil) by driving alone in an SUV is to help the enemy. The author feels that not enough has been done to prevent further catastrophic terrorist attacks. He argues that Americans have been led to believe that the current war can best be fought if we go about business as usual, pay less in taxes, and continue to buy consumer goods, even if they tie us to regimes in the Middle East known to be financing terror. This book is filled with controversial and perhaps politically incorrect statements, and each essay is likely to provoke a good argument.
