The nation that will insist upon drawing a broad line of distinction between the fighting man and the thinking man is liable to find its fighting done by fools and its thinking by cowards.
-- Sir William Francis Butler
The United States military currently views cyberspace as the “fifth domain” of warfare (alongside land, air, sea, and space), and the Department of Defense, the National Security Agency, and the CIA all field teams of hackers who can, and do, launch computer virus strikes against enemy targets. As recent revelations have shown, government agencies are joining with tech giants like Google and Facebook to collect vast amounts of information, and the military has also formed a new alliance with tech and finance companies to patrol cyberspace. Shane Harris offers a deeper glimpse into this partnership than we have ever seen before, and he explains what the new cyber security regime means for all of us who spend our daily lives bound to the Internet—and are vulnerable to its dangers.
