Former US national security advisor Sandy Berger believes the idea that Washington is able to scrap the recent international nuclear deal with Iran and resume negotiations for a better deal is a "chimera".
"I find it very hard to envision European leaders talking to their CEOs saying: sorry, you can't go into Iran yet because of American politics. I think the fact is it will unravel the sanctions," Berger said in a recent interview with Euronews.
