Retired US Navy Admiral William McRaven, best known for commanding the 2011 raid that killed Osama bin Laden and for his viral 2014 commencement speech 'Make Your Bed,' has released a new book titled 'Duty, Honor, Country & Life: A Tribute to the American Spirit,' collecting speeches that reflect on the values he believes still unite Americans. Speaking to PBS NewsHour, McRaven explained that he added the word 'Life' to the title — drawn from General Douglas MacArthur's famous 1962 address to West Point (the US military academy) — to emphasise that the ideals of duty, honour, and country must be lived out in everyday existence. Despite what he described as a polarised political climate, McRaven expressed cautious optimism, saying that Americans he meets across the country, particularly young people, still broadly share values of equality, justice, and the rule of law.
