In 1966, [[Ralph Schoenman]] persuaded [[Bertrand Russell]] to convene his [[Russell Tribunal|war crimes tribunal]] to judge United States involvement in the [[Vietnam War]].{{sfn|Horowitz|2011|p=146–53}} Horowitz would write three decades later that he had political reservations about the tribunal and did not take part. He described the tribunal's judges as formidable, world-famous and radical. They included [[Isaac Deutscher]], [[Jean-Paul Sartre]], [[Stokely Carmichael]], [[Simone de Beauvoir]], [[Vladimir Dedijer]] and [[James Baldwin]].{{sfn|Horowitz|2011|p=147–53}} In January 1966, Horowitz, along with members of the Trotskyist International Marxist Group, formed the [[Vietnam Solidarity Campaign]].<ref>{{Cite web|url=https://www.historyextra.com/period/20th-century/britain-at-war-over-vietnam/|title = Britain at war over Vietnam}}</ref> The Vietnam Solidarity Campaign organized a series of protests in London against British support for the [[Vietnam War]].

While in London, Horowitz became a close friend of Deutscher, and wrote a biography of him.<ref name="WSarchive">{{cite web|url=http://www.encyclopedia.com/doc/1G1-155477123.html|title=Confronting the enemy within|last=Soupcoff|first=Marni|date=November 20, 2006|publisher=Western Standard|access-date=January 8, 2010}}</ref><ref>''Isaac Deutscher: The Man and His Work.''

In January 1968, Horowitz returned to the United States, where he became co-editor of the New Left magazine ''[[Ramparts (magazine)|Ramparts]]'', settling in northern California.<ref name="nord1" />

During the early 1970s, Horowitz developed a close friendship with [[Huey P. Newton]], founder of the [[Black Panther Party]]. Horowitz later portrayed Newton as equal parts gangster, terrorist, intellectual and media celebrity.<ref name="nord1" /> As part of their work together, Horowitz helped raise money for, and assisted the Panthers with, the running of a school for poor children in [[Oakland, California|Oakland]]. He recommended that Newton hire [[Murder of Betty Van Patter|Betty Van Patter]] as bookkeeper; she was then working for ''Ramparts''. In December 1974, Van Patter's  battered, decomposed body was found on a beach in [[San Francisco Bay]]; she had been murdered. It is widely believed that the Panthers were responsible for her murder, a belief also held by Horowitz.<ref name="nord1" /><ref>{{cite web|url=http://www.thenation.com/print/article/david-horowitzs-long-march|title=David Horowitz's Long March|date=15 June 2000|publisher=Thenation.com|access-date=April 23, 2013|last1=Sherman|first1=Scott}}</ref><ref>{{Cite magazine |url=https://books.google.com/books?id=recDAAAAMBAJ&pg=PT28 |title=The Strange Journey of David Horowitz |magazine=[[Mother Jones (magazine)|Mother Jones]] |last1=Browning |first1=Frank |date=May 1987 |pages=27–38}}</ref><ref>Pearson, Hugh (1994).
