a duty' to actively oppose the war by any means." According to Ronald Christenson, a political science professor at Gustavus Adolphus College, Falk "invoked the Nuremberg precedent to argue that there is a right of individuals to stop crime 'even by creating a lesser crime.'" Ayatollah Khomeini in 1979 In early 1979, when Falk was a professor of International Law at Princeton, he visited Iranian Revolution leader Ayatollah Ruhollah Khomeini at his home on the last day of Khomeini's exile in France. In a February 1979 New York Times op-ed, published after Khomeini had returned to Iran, Falk wrote: "The depiction of him as fanatical, reactionary and the bearer of crude prejudices seems certainly and happily false." Falk commented that Khomeini's "entourage was uniformly composed of moderate, progressive individuals" and that "having created a new model of popular revolution based, for the most part, on nonviolent tactics, Iran may yet provide us with a desperately-needed model of humane governance for a third-world country." The New York Times gave Falk's article the headline "Trusting Khomeini", which Falk did not see before its publication. Falk said he received hate mail and death threats for some years afterwards because of the headline, not the article itself. By the end of 1979, Khomeini had become Supreme Leader of Iran and begun removing moderates from his circles, arresting and even killing political opponents and supporting students who took over the U.S. embassy in Tehran, holding American hostages for 444 days. Falk was criticized for having supported Khomeini. Around 1982, Falk called the Iranian government "the most terroristic since Hitler." In 2017, Falk told the Iranian Tasnim News Agency, "I believe one of the lasting legacies of Imam Khomeini was to give authoritative priority to the Palestinian struggle." 9/11 and the Bush administration In 2004, Falk signed a statement released by the organization 9/11 Truth, which called for a new investigation into the September 11 attacks. Falk confirmed his support for the statement in 2009. Falk contributed the preface to David Ray Griffin's book The New Pearl Harbor: Disturbing Questions About the Bush Administration and 9/11 (2004) which maintains that the George W. Bush administration was complicit in the September 11 attacks. Griffin believes that the Twin Towers were brought down by a controlled explosion. In the preface to The New Pearl Harbor, Falk wrote: "There have been questions raised here and there and allegations of
