SIR! NO SIR! demonstrates the unbelievable scope and power of the anti- war movement within all branches of the American military during the Vietnam War era. This documentary serves as a reminder for those of us who lived through this turbulent period of American history, and provides a cogent and factual historical record for those who were not yet born. Contemporary American pundits on the Far Right would like to see these truths silenced...permanently. The film shows that anti-war sentiment and anti-war activity permeated all sectors within the American Military establishment, and many brave men sacrificed their careers, and their very lives to stop our country's unnecessary and immoral war in South East Asia. One thing that struck me while watching the film, is that today, huge media conglomerates are being owned and operated by fewer individuals and groups, and how easy it has become to suppress and distort America's long history of dissent. These days, any critical examination of this country's involvement in foreign entanglements is perceived as disloyalty to the troops. Nothing can be farther from the truth, and SIR! NO SIR! shows that the genesis of this particular heresy began in the 1960's as those in power attempted to silence opposition to one of America's most unpopular wars. The film also boasted many Special Features which helped to reaffirm the theme that there was a concerted and intelligent opposition to the war in Vietnam , and this view was shared by a significant portion of this nation's fighting forces. Great film.
