LEE COUNTY, Fla. - One of the most anticipated publications of the year is now on bookstore shelves all across the country.

At Books-A-Million in the Page Field Commons, a steady stream of customers came in to purchase a copy of former president George W. Bush's new memoir, "Decision Points."  Store manager Kelly Young said it may be the most anticipated book since last year's final installment of the popular "Twilight" vampire series.

Young said more customers were expected Wednesday, after Bush appeared on today's Oprah Winfrey show.

"A lot of people don't think I can read, much less write," Bush joked to Winfrey during the show, which aired on WINK-TV.

As in the book, Bush also recounted the mistakes of his presidency, saying he still feels "sick" about the fact no weapons of mass destruction were found in Iraq. His response to Hurricane Katrina could have been quicker, he said, and he acknowledged he didn't see the financial meltdown coming.

No stranger to harsh criticism, Bush had nothing negative to say about President Barack Obama, whom Winfrey famously supported in 2008.

"I didn't like it when people criticized me," Bush said. "And so you're not going to see me out there chirping away (at Obama). And I want our president to succeed. I love our country."

Largely out of the public view since he left office, Bush is now vigorously promoting his book, with planned appearances in Illinois and Ohio later this week and as the featured author at the Miami Book Fair International this weekend.

Among the memoir's revelations, Bush confirms the target of a 2007 Israeli airstrike was a Syrian nuclear reactor and the suggests he quietly approved the action. He also reveals that Israel first asked the U.S. to bomb the site, but his administration refused.

The Syria section is just a small part of the book generating buzz for its surprising candor, while Bush's continued defense of harsh tactics used against terrorist suspects - such as waterboarding - has created an uproar in some areas, especially Europe.

Israel, one of the few places Bush remained popular throughout his term, has been far kinder. Israeli media have focused on the book's warm praise for ex-Prime Minister Ariel Sharon, his support for Israel's tough crackdown on Palestinian militants in the last decade and his animosity toward the late Palestinian leader, Yasser Arafat.

More than 2,000 copies of "Decision Points" sold by the time Bush left a Dallas bookstore at 11 a.m. Tuesday, said David Drake, a spokesman for the Random House Inc. imprint Crown Publishers. The former president was able to sign copies for 1,300 customers and provided signed bookplates for 500 others, said Drake, who added that the remainder of the crowd he estimated at 2,500 received instructions for getting a bookplate later.
