Recent Wars: Vietnam & Elsewhere

In the USA many feel it is injudicious, even treasonous, to criticize the wars now being waged by our brave uniformed men & women. But 35 years ago the USA was engaged in a distant intervention in Southeast Asia. Was the Vietnam war a grave mistake? Don't look to John McCain for a clear answer: he was a war victim, but also an active aggressor (dutifully piloted 23 bombing missions). His father served as Commander-in-Chief, Pacific Command (CINCPAC), in charge of unified US & South Vietnam (RVN) forces; the person responsible operationally for waging the war from 1968-1972. Was the US war in Vietnam a grave mistake? Was it fundamentally wrong? ... a criminal enterprise? Powerful Americans avoid the nasty facts (millions killed directly, continued crippling from landmines & dioxin pollution); if not citing US heroism, they'd like to forget about that war.
