Diane Sawyer quietly debuted on ABC's World News tonight by interviewing one of the world's craziest powerful men (or is it most powerful crazy men?), Iranian president Mahmoud Ahmadinejad. So, how'd she do? Pretty good, says the Times' Alessandra Stanley. Sawyer displayed her trademark "twinkly warmth," Stanley writes, while questioning Ahmadinejad on Iran's nuclear ambitions, but still managed to push him when he evaded her questions. In the end, Stanley says, Sawyer made it clear how she will handle her new job, by emphasizing "exotic travel and big 'gets.'"
