Declassified government files reveal Washington were planning how to trigger conflict with Moscow by buying up planes used by the Soviet Union.
These aircraft would the be used in a “provocation operation” in which they would appear to attack the US.
Government bosses would then be able to use it as an “excuse for a US intervention”, the CIA document reveals.
The revelation comes as part of the JFK file dump as US President Donald Trump allowed thousands of Cold War era files to be opened to the public.
Most of the files cover the assassination of John F Kennedy, but they also cover other shocking secrets hidden by the CIA.
