In an odd way, this rise of ISIS, followed by their defeat, crystallized even further the need to tell the long, winding, conflicted, and utterly cou… - Pete Hegseth

I'm privileged to call many of these warriors friends. These are great Americans. They are heroes- even if they reject that title. Working on this venture with them has made me even more proud to be an American- which I didn't know was possible. These men and women are true patriots and true warriors. Like those before them, some may have joined the military for a cause or for the college money, but that soon became secondary to the brotherhood of war. When the bullets start flying, there are no Republicans or Democrats, whites or blacks- only brothers, the greatest of our men and women. This book is dedicated to everyone who has answered America's call. Who put it all on the line- and especially those who gave the ultimate sacrifice on the altar of freedom. We never, ever forget them. Warriors forever, in life and death. May their stories live forever.

During the writing of this book, America's two-decade war in Afghanistan came to an inglorious end. After thousands of lives lost, and trillions of dollars spent, the Islamist Taliban are back in charge. It's a humbling, if illuminating, reality. Like most Americans, I was eager for "the folks who knocked those buildings down, to hear all of us soon," as President George W. Bush said atop the rubble of the World Trade Center in 2001. American military might quickly toppled the Taliban, and Al Qaeda scurried into Pakistan. What followed was a nineteen-year experiment in Afghanistan, during which I had a front-row seat.

We all come at the subject of education- of "school"- with our own backgrounds. The Left calls this concept "implicit bias." They cynically apply it to race and gender, but it's very true when it comes to schooling. The goal of this book has been to challenge our long-held assumptions- our biases- about what we think is good for kids, and good for this country.
