Tehran might be a “relatively short time away” from having a nuclear weapon, a former CIA chief said on Monday.

“Iran is a very serious problem already and will be a much bigger one very shortly,” James Woolsey — who served as a senior adviser to President Donald Trump during the 2016 general election campaign and pre-inauguration transition period — told CNN’s Wolf Blitzer.

Asked about Iran’s compliance with the July 2015 nuclear deal, Woolsey — the head of the CIA from Feb. 1993 to Jan. 1995 during former President Bill Clinton’s first term in office — stated, “I think that the chance that the Iranians are keeping their word is about as close to zero as diplomatic relationships go.”
