(CNN) Republicans quickly pounced on some controversial details from former Defense Secretary Bob Gates' new book in which he highlights an admission from former Secretary of State Hillary Clinton that he found "dismaying" and fiercely lambasts Vice President Joe Biden.
Gates, who led the Pentagon under two presidents from 2006 to 2011, also offered scathing critiques of President Barack Obama and Congress in the memoir, "Duty: Memoirs of a Secretary at War," which is set to hit bookshelves next week.
According to longtime Washington Post reporter Bob Woodward, who reviewed the book Gates said Clinton told Obama that she opposed the 2007 troop surge in Iraq for political reasons, as she was running against Obama in the Iowa presidential caucuses at the time.
"The president conceded vaguely that opposition to the Iraq surge had been political," Gates writes. "To hear the two of them making these admissions, and in front of me, was as surprising as it was dismaying."
In early 2007, Washington was split on whether to increase the number of troops in Iraq or to start bringing them home. Clinton was among Senate Democrats, including Biden and Obama, who opposed boosting troop levels.
"I am not in favor of sending more troops to continue doing what our young men and women have been told to do, with the government of Iraq pulling the rug out from under them when they actually go after some of the bad guys. I am not in favor of doing that unless it's part of a larger plan," she said in December 2006 on NBC's "Today."
"Everyone knows there is no military solution to the difficulties we face in Iraq," she continued, saying there needed to be a broader plan that "includes resolving some of the political issues."
According to CNN/ORC International polling in March 2007, 83% of Democrats opposed President George W. Bush's plan to send about 20,000 more U.S. troops to Iraq.
For Republicans eager to get a head start on defining Clinton in anticipation of her possible 2016 presidential run, Gates' book became quick fodder for negative attacks, even though Gates also complimented in his memoir.
America Rising PAC, an independent conservative group, e-mailed reporters Tuesday afternoon, claiming her admission as quoted in Gates' book "is sure to undermine her attempt to position herself as 'serious' on foreign policy issues ahead of a likely 2016 run."
The Republican National Committee soon followed with its own e-mail containing a satirical question: "We're hearing Hillary Clinton made a decision based on politics. Which one of her Super PACs will respond?"
"Hillary Clinton has a history of making decisions based on politics instead of principle," RNC spokeswoman Kirsten Kukowski said in a separate comment. "It will be interesting to see how she addresses this with voters who have a long memory of the Clinton ways."
Garrett Marquis, a spokesman for another anti-Clinton group, Stop Hillary Clinton, argued the book excerpt proved Clinton is "disingenuous and deceitful."
"She will do anything, including mislead the country, by putting her political ambitions ahead of the safety of Americans at home and abroad," he said.
David Brock, founder of Correct The Record, a project the frequently defends Clinton, pointed out Gates' admiration for Clinton in the book.
"Gates's trust in her seems to be epitomized by the high praise he reserved for her," Brock said.
"The President, the Vice President, Secretary Clinton all took office on a promise to end the war in Iraq and defeat al Qaeda so that we could end the war in Afghanistan. That's what they've done," DNC Communications Director Mo Elleithee said, adding "that's what people will remember."
In his book, Gates otherwise praised Clinton in a way that "might be used in a political endorsement," Woodward wrote in his review.
Gates wrote: "I found her smart, idealistic but pragmatic, tough-minded, indefatigable, funny, a very valuable colleague, and a superb representative of the United States all over the world."
And at Gates' farewell ceremony in 2011, he had high praise for Clinton, saying she's become a cherished colleague and a good friend.
He was not as complimentary about the Vice President, however, according to Woodward and Thom Shanker of the New York Times, who also reviewed the book.
While Gates calls Biden "a man of integrity," he reportedly writes, "I think he has been wrong on nearly every major foreign policy and national security issue over the past four decades," according to Shanker's review.
Biden was tapped to be Obama's running mate in 2008 largely because of his foreign policy experience. Biden was serving as chairman of the Senate Foreign Relations Committee at the time and had been in the Senate for six terms.
According to Woodward's review, Gates expresses "outright contempt" for the Vice President and "Biden is accused of 'poisoning the well' against the military leadership."
Gates named a specific example of what he considered Biden's poor judgment in an opinion piece for the Wall Street Journal on Tuesday. He said Biden preferred a "strategy of reducing our presence in Afghanistan to rely on counterterrorist strikes from afar."
Gates said such "'Whac-A-Mole' hits on Taliban leaders weren't a long-term strategy."
National Security Council spokeswoman Caitlin Hayden defended Biden in response to the book.
"The President disagrees with Secretary Gates' assessment - from his leadership on the Balkans in the Senate, to his efforts to end the war in Iraq, Joe Biden has been one of the leading statesmen of his time, and has helped advance America's leadership in the world. President Obama relies on his good counsel every day," she said.
Asked about Gates' opinion of Biden, Sen. John McCain told CNN's Wolf Blitzer, host of The Situation Room, that he has the "greatest affection" for Biden ... and he's one of the finest men that I've known."
"But he has been wrong on a lot of these issues, there's very little doubt about that, going back to Desert Storm," the Arizona Republican said.
McCain was pressed on whether it's fair to say Biden has been wrong on every issue over the past four decades.
"I don't want to recount them," McCain said, laughing. "But he has been wrong on a number of occasions, and he was one of the factors in the whole removal of all of our troops from Iraq."
