A tale of two quagmires : Iraq, Vietnam, and the hard lessons of war

Is Iraq becoming another Vietnam? Author Kenneth Campbell received a Purple Heart after serving 13 months in Vietnam.

He then spent years campaigning to get the US out of the war.

Here, Campbell lays out the political similarities of both wars.

He traces the chief lessons of Vietnam, which helped America successfully avoid quagmires for thirty years, and explains how neoconservatives within the Bush administration cynically used the tragedy of 9/11 to override the "Vietnam syndrome" and drag America into a new quagmire in Iraq.

In view of where the U.S. finds itself today - unable to stay but unable to leave - Campbell recommends that America re-dedicate itself to the essential lessons of Vietnam: the danger of imperial arrogance, the limits of military force, the importance of international and constitutional law, and the power of morality.
