A newly drafted United States nuclear strategy that has been sent to President Trump for approval would permit the use of nuclear weapons to respond to a wide range of devastating but non-nuclear attacks on American infrastructure, including what current and former government officials described as the most crippling kind of cyberattacks.

President Obama's administration came to office with the world on fire. Confront and Conceal is the story of how, in his first term, Obama secretly used the most innovative weapons and tools of American power, including our most sophisticated—and still unacknowledged—arsenal of cyberweapons, aimed at Iran's nuclear program.

Confront and Conceal—with an updated epilogue for this paperback edition—provides an unflinching account of these complex years of presidential struggle, in which America's ability to exert control grows ever more elusive.
