The New York Times runs a story today on how the U.S. has refined our war plans to fight in cities. We are no longer talking of razing cities, and have taken into account--with more seriousness than ever before--Sun Tzus warning: "The worst policy is to attack cities." So we are relying more than ever on intelligence, tight coordination, rapid movement, and selective targeting. The Defense Department has published a massive document (150 pages), called a "Doctrine for Joint Urban Operations," on the subject. Worth having a look.
