Landau worked as a volunteer intern for
The Jerusalem Post in 1967, after refusing to return home during the Six-Day War despite his family's entreaties. While working for
The Jerusalem Post, he was one of the organizers who staged a walkout of journalists in 1990, claiming the paper's new owner was commandeering its editorial line and seeking to turn the paper into a platform for right-wing views. Landau's book,
Piety and Power: The World of Jewish Fundamentalism, was published in 1993. In 1996, Landau collaborated with the former prime minister
Shimon Peres on his memoirs,
Battling for Peace. Landau replaced Hanoch Marmari as editor-in-chief of
Haaretz in 2004. He stepped down in April 2008 but remained on the editorial staff. He was succeeded by
Dov Alfon. In 2014, Landau published
Arik: The Life of Ariel Sharon, a biography of
Ariel Sharon commissioned by the New York publishing house
Alfred A. Knopf. Landau was appointed
Officer of the Order of the British Empire (OBE) in the
2014 Birthday Honours for services to advancing UK/Israel understanding and peace in the Middle East. ==Controversy==
