During the Vietnam War, I served in combat in the dark jungles of that land where the killing fields existed. That experience unlike music did not calm the soul. I recall reading Lincoln's First Inaugural Speech in 1861 as he faced Southern Succession and the coming conflict of the Civil War. In it he tried to reconcile the horror of the war, its killings, by looking forward to the time we could be a united nation once again by referring to "...the better angels of our natures".
Sadly in wars "...the better angels..." do not readily appear as soldiers slug it out, killing each other .
Such was the Vietnam War. That war, the basis for my thriller mystery novel, The Phung Hoang Legacy, serves to explain, trying to find the "better angels" within our selves.
