In 1968 Capa published a book called "The Concerned Photographer". As evidenced in his work, this title sums up his approach to photojournalism. Among the many events and causes Capa documented were the oppression of the Perón regime in Argentina and the subsequent revolution, Israel's Six-Day War, the plight of the Russian Orthodox Church under Soviet rule, and the education of mentally retarded children. He also took great interest in politics and documented the presidential campaigns of Adlai Stevenson and John F. Kennedy, along with Kennedy's first one hundred days in office.
