Regarded as a premier tactician, Johnson became skeptical that the level of resources given to the Vietnam War, much of which went into 'find, fix, and destroy the big main force units' operations, could deliver victory. Johnson came to believe that the Communist forces held a trump card, because they controlled whether there were engagements with US forces, giving an option to simply avoid battle with US forces if the situation warranted it.

Eisenhower's second adviser George Kistiakowsky, Kennedy adviser Jerome Wiesner and many scientists that took part in the Manhattan project.

Document 7: Pentagon Papers: The Pentagon Papers, officially titled United States – Vietnam Relations, 1945–1967: A Study Prepared by the Department of Defense, is a United States Department of Defense history of the United States' political-military involvement in Vietnam from 1945 to 1967. The papers were released by Daniel Ellsberg, who had worked on the study; they were first brought to the attention of the public on the front page of "The New York Times" in 1971. A 1996 article in "The New York Times" said that the "Pentagon Papers" had demonstrated, among other things, that the Johnson Administration "systematically lied, not only to the public but also to Congress".
Document 8: Green Light Teams: Green Light Teams were Special Forces squads containing members of the U.S. Army, U.S. Navy, and the U.S. Marines during the height of the Cold War with the Soviet Union. These Green Light Teams, also referred to as Atomic Demolition Munitions Specialists, were trained to advance, arm, and deploy Special Atomic Demolition Munitions behind enemy lines. These Atomic Demolition Munitions, also known as ADMs and backpack nukes, are smaller, and more portable nuclear weapons created by the United States beginning in 1954. These initial Atomic Demolition Munitions required large teams of trained soldiers and still weighed hundreds of pounds. The United States of America’s nuclear weapons developers were encouraging of the Military’s desire for tactical nuclear weapons. The President of one of these nuclear weapons developers, James McRae of Sandia Corporation, was among those inspiring the further development of tactical nuclear weapons, asserting: “greater emphasis should be placed on small atomic weapons”. The development of the Davy Crocket nuclear device, an atomic weapon with a sub-kiloton energy yield that can be transported on the back of a jeep, served as a pre-cursor to the eventual final product foreseen by the Military, the Mk-54 Special Atomic Demolition Munition. The Davy Crocket’s lightweight Mark-54 composition was encouraging to the further production and advancement of smaller Special Atomic Demolition Munitions, such as the W-54 version which could be manned by a single trained soldier.
