Abstract
On March 23, 2010, President Barack Obama signed the Affordable Care Act (ACA) into law. Implications of the ACA on mental health care for 9.7 million military active-duty, reserve, and family members and 22.2 million veterans, as well as 1.3 uninsured veterans, is reviewed in light of a major crisis. The authors trace historical roots of the ACA to the World War II generation and efforts to transform the mental health care system by implementing hard-won war trauma lessons. The authors posit 9 principles reflected in the ACA that represent unfulfilled generational war trauma lessons and potential transformation of the military and national mental health care systems.
