In the four-page note released Tuesday ahead of the book launch next month, the former secretary of state reflects on her political career, her time in the Obama administration and her vision for the country moving forward.

“I wrote it for anyone anywhere who wonders whether the United States still has what it takes to lead,” Clinton writes of her upcoming book. “For me, the answer is a resounding ‘Yes.’ Talk of America’s decline has become commonplace, but my faith in our future has never been greater.”

“Everything that I have done and seen,” she adds, “has convinced me that America remains the ‘indispensable nation.’”

Clinton, who will most likely be a front-runner for the Democratic presidential nomination if she chooses to run in 2016, said the book is largely about the decisions she and President Barack Obama made while she was at the State Department.

She explicitly mentions the May 2011 Navy SEAL raid on Osama bin Laden’s compound, which she said was “as crisp and courageous a display of leadership as I’ve ever seen.”

Clinton also addresses her “unexpected partnership and friendship with my former rival Barack Obama,” the man who defeated her in a contentious 2008 presidential primary but later asked her to join his Cabinet as the country’s top diplomat.

“Hard Choices” comes out on June 10.
