Lennon was stung by the criticism he received from the New Left. Having campaigned for world peace with Ono throughout 1969, he began to embrace radical politics after undergoing primal therapy in 1970. In a conversation with British activist Tariq Ali in January 1971, he said of "Revolution": "I made a mistake, you know. The mistake was that it was anti-revolution." Lennon then wrote "Power to the People" to atone for the perceived apathy of "Revolution", and instead sung: "You say you want a revolution / We better get it on right away." After moving to New York in 1971, he and Ono fully embraced radical politics with Chicago Seven defendants Jerry Rubin and Abbie Hoffman. Lennon abandoned the cause following Richard Nixon's victory in the 1972 presidential election and he subsequently denounced revolutionaries and radical politics as useless. In the final interview he gave before his murder in December 1980, Lennon reaffirmed the pacifist message of "Revolution", saying he still wished to "see the plan" for any proposed revolution. With reference to Lennon's comments in this interview, MacDonald wrote in 1994: "Tiananmen Square, the ignominious collapse of Soviet communism, and the fact that most of his radical persecutors of 1968–70 now work in advertising have belatedly served to confirm his original instincts."
