Vindication on what evidence?

Bush proclaims, "History will vindicate me!" Jacob Weisberg of Newsweek responds, "How can historians tell?" One thing Bush is really good at is secrecy. But Bush's reputation -- based on why he invaded Iraq, why he expanded 9-11 into a global War on Terror, and his role in today's financial mess -- can't be rehabilitated (if at all) until historians can look at what role Bush had in these events. Was Bush planning for a noble outcome that went disastrously wrong? Did these things happen because of Bush's own incompetence? Was he truly a puppet of Cheney? Why was he a moderate Texas governor yet a polarizing president? Why did he order or permit torture? These questions needs answers for Bush's historical status to be properly assessed and his secrecy works against that. Don't count on a book by Bush or David Frost style interviews. His memory is too poor and he is too unreflective to have kept a diary.
