While America Sleeps is a book by Donald Kagan and Frederick Kagan, published September 2000. They argue for a policy of strengthening U.S. defense and a willingness to use force. Michael Lind has argued that the book contributed to neoconservative thought in U.S. foreign policy.[1]

Two similarly titled works were published around the time of World War II: While England Slept (1938), by future British Prime Minister Winston Churchill, and Why England Slept (1940), by future U.S. President John F. Kennedy, at the time a Harvard University undergraduate student.
