He supported US involvement in the Second World War and initially supported a hard-line against Communism, but moderated over time.[149] However, Friedman did state in a 1995 interview that he was an anti-interventionist.[150] He opposed the Gulf War and the Iraq War. In a spring 2006 interview, Friedman said the US’s stature in the world had been eroded by the Iraq War, but that it might be improved if Iraq were to become a peaceful and independent country.[151][149]
