He said I hate the war and so does Eleanor, but we won't be safe till everybody's dead.
Time magazine "felt a need to warn its readers," describing the album as echoing "the mendacious Moscow line." Eleanor Roosevelt said the songs were clever "but in poor taste." After Russia and the U.S. were allies, Bernay strongly supported the war and released the pro-war Dear Mr. President. Bernay said: "Now is our chance to make up with Franklin Roosevelt, who is not really such a bad guy." The title song, "Dear Mr. President", a solo by Pete Seeger, expressed Bernay's newfound support for the war effort. In 1943, looking for a larger audience he turned to jazz. Recording "the most celebrated jazz soloists," with Harry Lim as producer, in a span of three years Keynote "produced some of the finest jazz recordings of the era." The Lester Young quartet session of 1943 was Keynote's first jazz effort and marked Young's first as a leader. Dinah Washington's recording debut was with Keynote at the end of 1943. In a session with the Lionel Hampton band, she recorded Evil Gal Blues.

He has been described as a member of the Communist underground. He testified that he was a member of the Communist Party from 1936–1938, and was publisher for the official Party organ, The New Masses during that time. He employed both Irving Lerner and Arthur Adams at Keynote. Lerner had to leave the Office of War Information after being caught photographing the cyclotron at the University of California, Berkeley. Adams, a Sovietatomic spy, was hired in 1945 for $75/week as a plastics consultant. In 1945 he helped Adams escape FBI surveillance and leave New York City, accompanying him to Chicago. He advanced Adams money to make his way to Portland, Oregon, where he was stopped by the FBI trying to leave the country. Bernay claimed that he never suspected Adams was a spy, although he knew he had been under constant surveillance. The conclusion of the HUAC was that "it is unquestionable that persons associated with Adams...furnished him with assistance with his espionage activities."
In 1986 and 2013 there were reissues of the 1941–1947 Keynote jazz collection. The reviews were strongly positive, noting that Keynote "made a very strong contribution to the world of jazz," and the reissue "contributed greatly to documenting the jazz history of 40s America." He released the first early Almanac albums; he helped introduce artists such as Woody Guthrie, Pete Seeger, Burl Ives, Lee Hays, and Josh White. They used song "as a weapon in the struggle for a fair, equal and peaceful society" and "led to a rediscovery of our popular musical roots...and a retelling of our American story."
