Paul Krugman on recent turmoil in Egypt:"I don’t know anything, have no expertise"

Paul Krugman is an Op-Ed columnist for The New York Times. I admire his latest statement on the situation in Egypt. In a short post on January 28, 2011, he said the following: "I don’t know anything, have no expertise." It is rare to see a pundit of his level making such a sobering statement on current major political issues that place the US and its international political outlook in limbo, to say the list. I am just wondering if Mr. Krugman's remark was a reply to readers' questions or just a blunt  and sobering statement from a scholar who knows his limit. Only time will tell.
