CIA chief warns Trump that scrapping Iran deal would be "dangerous"

During a wide-ranging interview with the BBC that aired Wednesday, the outgoing U.S. spy chief also cautioned that Russia should not be trusted.

“First of all for one administration to tear up an agreement that a previous administration made would be unprecedented,” Brennan said. “It would be the height of folly if the next administration were to tear up [the Iran] agreement.”…

Brennan also advised the incoming administration to be “wary of Russian promises.”

“Russia is a country that will pursue its national interests frequently to the detriment of the interests of the peoples of the countries wherein it operates,” he said. “Russian promises in my mind have not given us what it is they have pledged.”
