Query: Provacative View of the Vietnam War

Michael Lind would seem like an unusual person to reinterpret the titanic struggle over Vietnam. He is a writer, poet and left-of-center journalist who feels that despite the enormous cost in lives and material and the deep flaws in American policy, the war still served a purpose. Lind views the war as part of the Cold War and feels that we were sure to lose some battles in the fifty-year campaign to contain Communism. He divides the war into two distinct phases, an overwhelmingly guerilla insurgency in the years before 1968's Tet Offensive, and a more conventional, territorial land war that began after Tet. Lind believes that the strategy employed in the first phase was horribly misguided, and that afterwards, Congress and the American people had lost faith in the entire sorry affair. The Necessary War is a well-argues polemic that challenges conventional wisdom.
