America's War on Terror, launched in response to the September 11, 2001, attacks on the World Trade Center and the Pentagon, has had a staggering impact on our world. The Costs of War Project at Brown University, which I helped found, paints as full a picture as possible of the toll of those "forever wars" both in human lives and in dollars. The wars, we estimate, have killed nearly one million people, including close to 400,000 civilians in Afghanistan, Iraq, and Pakistan alone. Worse yet, they sickened or injured several times more than that — leading to illnesses and injuries that, we estimate, resulted in millions of non-battlefield deaths.
And don't forget that those figures include dead and wounded Americans, too. Most of us, however, have little awareness of any of this. If you live outside the archipelago of American military bases that extends across this country and the planet — an estimated 750 of them outside the U.S. on every continent except Antarctica — it's easy enough not to meet stressed-out military service members and their families. It's easy enough, in fact, not to grasp just how America's wars of this century rippled out to touch military communities.
