"The Russians are coming" is a phrase attributed to United States Secretary of Defense James Forrestal in 1949.
"[1] Forrestal allegedly uttered those words while suffering from mental illness, not long before committing suicide.
The allegation originated with Forrestal's bitter political enemy, columnist Drew Pearson, and has been verified by no other person.
This is what Townsend Hoopes and Douglas Brinkley have to say about the episode in their 1992 book, Driven Patriot, the Life and Times of James Forrestal: Pearson had, in fact, decided to fire his heaviest ammunition in a radio broadcast on April 9.
In subsequent newspaper columns he asserted that Forrestal made three suicide attempts while in Florida – by drug overdose, by hanging, and by slashing his wrists.
