The Vietnam War

They asked their company commander, "Why are we here?" They did not understand nor wanted to be in the Vietnam War.
Looking back fifty-three years, he explains the background and the causes of the War. How and why the US became mired down in turbulent times of student unrest, political assassinations, anti-war protests led by Jane Fonda, Martin Luther King and other notables, as well as Civil Rights marches, corrupt and incompetent Vietnamese governments, meanwhile Presidents and Generals quietly had doubts about the War.

So, he quietly mentioned to his soldiers, "Let's do our jobs and go home." They did their jobs, went home, and nobody cared.
This book is not for those expecting Rambo-type heroics. Instead, its author and his men served their country not as fighters engaged in active combat, but as engineers, quietly going about the nuts-and-bolts business of building and repairing roads, bridges, and infrastructure. They accomplished their missions through difficult conditions including heavy workloads, drug abuse, racism, doubts about the war, arguments, and heated discussions about getting the job done, and being homesick for love.

He then concludes with a suggestion for future wars.
