His third book was the autobiographical "Beating the Unbeatable Foe: One Man's Victory over Communism, Leviathan, and the Last Enemy", published in 1996. The foreword reproduces a letter in which US President Ronald Reagan, with whom Schwarz had been friendly for many years, wrote (on 4 January 1990): "Fred, you're to be commended for your tireless dedication in trying to ensure the protection of freedom and human rights." The book included accolades by William F. Buckley Jr., Reed Irvine, John Stormer, and others. In acknowledgement of Schwarz's influence upon Reagan's anticommunist policies and rhetoric, speechwriter Anthony R. Dolan sent Schwarz a copy of Reagan's Evil Empire speech with the note: “I thought you might like to see the oak tree that has grown from the acorn which you planted so many years ago.”
