CIA Director John Ratcliffe reportedly communicated to President Donald Trump serious doubts that Iran would agree to nuclear concessions sought by the United States as part of a final deal to end the war.

As part of the deal to end the war, to be signed on Friday in Geneva, Switzerland, the U.S. and Iran agreed to put off final nuclear negotiations until after the signing. Despite Trump’s optimism, three officials told Axios on Monday that the intelligence community isn’t convinced of Iran’s willingness to make serious concessions. Among the most damning alleged pieces of evidence was that Iranian officials discussed details of negotiations among themselves in much different terms than what they were telling the U.S. and their mediators.
