Translated from the German original, this scholarly but extremely disturbing analysis deserves to sit on the same shelf as John Nagl's Learning to eat Soup with a Knife, Neil Sheehan's A Bright Shining Lie and HR McMaster's Dereliction of Duty, each of which focus on different aspects of the US military failure in Vietnam.
Like Nagl and others, Greiner demonstrates how the US military was institutionally incapable of fighting a war on other than a massive conventional basis and its response to any situation was simply 'more', (bombs, artillery, troops, chemicals, Phoenix), to a stage where its doomed and blind approach to the Vietnamese insurgency (Nagl's term) and its approach to 'asymmetrical war' (Greiner's definition) led to strategic, tactical and moral bankruptcy and eventual widespread and massive murder of civilians, of which My Lai, Tiger Force and Operation Speedy Express were mere exemplars.
Greiner's hypothesis (comprehensively researched, footnoted and indexed) is unique in that he states that the use and escalation of massive force became indiscriminate and reached such a stage that the international rules of war (of which the US was a signatory) and the US military's own Rules of Engagement were effectively ignored and flouted, not just by GIs and junior officers, but all the way to the top of the US military hierarchy in Vietnam. He demonstrates how the obsession with body-count eventually led to the state of moral degeneracy where South Vietnamese civilians (the US's nominal clients after all)were regarded initially with disdain, then with contempt (universally 'gooks' and 'slopes' and worse) and then finally dehumanised altogether as 'if they are dead they must be VC', leading to widespread atrocities such as torture, rape and murder.
Greiner demonstrates that the US military collectively and institutionally lost its way (and its moral compass) in Vietnam and the obvious military and moral degeneration which reflected an unwinnable war being fought incorrectly and immorally resulted in indiscriminate, frequent and widespread slaughter of innocent civilians by infantry, artillery (e.g. indiscriminate 'Free Fire Zones') and air power (helicopter attacks as well as carpet bombing). Greiner's analysis is thorough and I think unarguable, especially in the confirming context of Nagl, Sheehan et al. Some of the translation is over-literal and a little ponderous(e.g. 'M16 storm weapons' (sic)), but that may also be a feature of the original German text, not always easy to translate without losing the original meaning.
A disturbing but necessary read and a vivid counterargument to the notion that the US always fought 'good' (i.e. moral) wars as well as
the increasingly prevalent notion that the war could have been won but the military were somehow 'prevented' from doing so.
Uncomfortable but necessary reading for serious students of the conflict and a significant addition to the literature on the Vietnam conflict.
