"Great nations need organizing principles, and 'Don't do stupid stuff' is not an organizing principle," Clinton told The Atlantic's Jeffrey Goldberg, knocking the Obama administration's foreign policy.
Faced with a second term dominated by foreign policy issues - namely the rise of extremism in Iraq, conflict between Israel and the Palestinians, and the increasing aggression of Russia - Obama has taken to describing his foreign policy doctrine as "Don't do stupid stuff."
Although Clinton added that Obama was "trying to communicate to the American people that he's not going to do something crazy" with the refrain, Goldberg writes that Clinton "repeatedly suggested that the U.S. sometimes appears to be withdrawing from the world stage" during the interview conducted this past week.
Clinton added, "I think that that's a political message. It's not his worldview," telling Goldberg, "I've sat in too many rooms with the president. He's thoughtful, he's incredibly smart, and able to analyze a lot of different factors that are all moving at the same time. I think he is cautious because he knows what he inherited."
Since releasing her new memoir in June, Clinton has slowly taken steps away from her former boss's positions. The tactic appears to be intentional: Obama's poll numbers are slipping and Clinton, who is widely considered the front-runner for the Democratic presidential nomination in 2016, needs to separate herself from the negative numbers.
The first split with Obama came during the Syria chapter of her book "Hard Choices," where Clinton articulates that she and the President disagreed on how to handle the "wicked problem" of arming Syrian rebels.
The "risks of both action and inaction were high. Both choices would bring unintended consequences. The President's inclination was to stay the present course and not take the significant further step of arming rebels," she wrote. "No one likes to lose a debate, including me. But this was the President's call and I respected his deliberations and decision."
In her interview with The Atlantic, Clinton went further than she does in her book and called the inaction in Syria a "failure."
"The failure to help build up a credible fighting force of the people who were the originators of the protests against Assad - there were Islamists, there were secularists, there was everything in the middle - the failure to do that left a big vacuum, which the jihadists have now filled," Clinton said.
During her time as secretary of state, Clinton advocated arming and vetting rebel groups fighting against Syrian President Bashar al-Assad. Obama, however, disagreed early in the conflict and the United States began arming the rebels in September 2013, after Clinton had left the State Department.
During the interview with The Atlantic, Clinton appears to put herself in between Obama and former President George W. Bush on military intervention.
"You know, when you're down on yourself, and when you are hunkering down and pulling back, you're not going to make any better decisions than when you were aggressively, belligerently putting yourself forward," Clinton said. "One issue is that we don't even tell our own story very well these days."
In July, a top White House aide said he didn't think Clinton was "trying to distance herself" from Obama.
Dan Pfeiffer, a longtime Obama aide and senior adviser, said the White House doesn't "assume that the Secretary Clinton or anyone else must agree 100% with the president on every single decision that he has ever made."
In addition to her breaking with Obama in her memoir, Clinton has used the book tour to draw more stark divisions.
"Every party in the White House has the responsibility during the time it's there to do the best we can, to lead and manage the many problems we face. And I think we did that in the first term," Clinton said last month in an interview with NPR. The answer, notably, did not include all of Obama's presidency in the answer.
On working and partnering with Obama in Iraq - something that was floated by the Obama administration - Clinton said in July that she was "not prepared" to work with Iran.
"I am not prepared to say that we go in with Iran right now, until we have a better idea what we're getting ourselves into," Clinton said during a televised CNN town hall meeting.
