In the revealing interview, Mr. Buffett discusses how he missed predicting the crisis and its effect on the financial system. He also shares thoughts on some of the main players, like Jamie Dimon and Ken Lewis; the logic behind the investments he made in late 2008, and how close the system came to collapse. He also talks about what he calls "the single most important decision in evaluating a business," his thoughts on the US dollar and Moody's, and why he sold Freddie Mac and Fannie Mae.
