Walters is known for "personality journalism" and her "scoop" interviews. In November 1977, she achieved a joint interview with Egypt's president, Anwar Al Sadat, and Israel's Prime Minister, Menachem Begin. According to The New York Times, when she went mano a mano with Walter Cronkite to interview both world leaders, at the end of Cronkite's interview, he is clearly heard saying: "Did Barbara get anything I didn't get?" Her interviews with world leaders from all walks of life are a chronicle of the latter part of the 20th century. They include the Shah of Iran, Mohammad Reza Pahlavi, and his wife, the Empress Farah Pahlavi; Russia's Boris Yeltsin and Vladimir Putin; China's Jiang Zemin; the UK's Margaret Thatcher; Cuba's Fidel Castro, as well as India's Indira Gandhi, Czechoslovakia's Václav Havel, Libya's Muammar al-Gaddafi, King Hussein of Jordan, King Abdullah of Saudi Arabia, and Venezuelan President Hugo Chavez, among many others. Other interviews with influential people include pop icon Michael Jackson, actress Katharine Hepburn, Vogue editor Anna Wintour, and in 1980 Sir Laurence Olivier. Walters considered Robert Smithdas, a deaf-blind man who spent his life improving the lives of other individuals who are deaf-blind, as her most inspirational interview.
Her television special about Cuban leader Fidel Castro aired on ABC-TV on June 9, 1977. Although the footage of her two days of interviewing Castro in Cuba showed his personality, in part, as freewheeling, charming, and humorous, she pointedly said to him, "You allow no dissent. Your newspapers, radio, television, motions picture are under state control." To this, he replied, "Barbara, our concept of freedom of the press is not yours. If you asked us if a newspaper could appear here against socialism, I can say honestly no, it cannot appear. It would not be allowed by the party, the government, or the people. In that sense we do not have the freedom of the press that you possess in the U.S. And we are very satisfied about that." She concluded the broadcast of the interview by remarking, "What we disagreed on most profoundly is the meaning of freedom—and that is what truly separates us." At the time, Walters kept quiet about seeing New York Yankees owner George Steinbrenner, pitcher Whitey Ford, and several coaches in Cuba, there to assist Cuban ballplayers.
