Let?s begin with a riddle. I?ve been everywhere. And nowhere. At the same time. Where was I?

 Las Vegas.

 It?s the only city in the world where, in a single evening, one can stroll through Saint Mark?s Square, ride to the top of the Eiffel Tower, and enjoy a view of the Empire State Building. Well, sort of.

 There?s certainly more to Vegas than gambling (or ?gaming,? as the locals prefer to call it). The casinos feature plenty of art, some real, some imitation. Galleries display real works by Monet, Manet (who hated it when he got Monet?s mail) and Renoir.

 But gambling is clearly the main attraction. You can bet on virtually anything: cards, dice, athletic contests. You can do simple wagers or fancy parlays. If you can predict it, you can make money on it, even exhibition baseball, where the players aren?t really even trying to win. The only thing you can?t bet on is something that?s already happened.

 And that?s what makes Vegas different from Washington. Here, you can make money on something that?s already happened. You simply have to claim to have foreseen it.
Just ask Richard Clark, or Ron Suskind and Paul O?Neill. They?ve all become best-selling authors by writing books, in 2004, explaining what the Bush administration should have done, and should not have done, in 2001, 2002 and 2003.

 And they all agree that last year?s war in Iraq was a critical mistake. Looking back, they say they were always looking forward. ?I blame the entire Bush leadership for continuing to work on Cold War issues when they back in power in 2001,? Clarke said on ?60 Minutes.? ?They wanted to work on the same issues right away: Iraq, Star Wars. Not new issues, the new threats that had developed over the preceding eight years.?

 For his part, former Treasury Secretary O?Neill says the administration was interested in invading Iraq from Day One. ?It was all about finding a way to do it. That was the tone of it. The president saying ?Go find me a way to do this,?? O?Neill told CBS.

 What a coincidence that this prescience is being revealed now, just as a presidential election gets underway, and when it?s likely to show President Bush in the worst possible light. But somehow, other possible predictions, ones that wouldn?t reflect badly on the president, didn?t make these books.
