The tragedy of LBJ was his insecurity and continued reliance on tools suited for a shrewd legislator rather than the Commander in Chief of the United States Armed Forces. It appears that he was intimidated by experts in the areas in which he knew the least -- military strategy, as just one example.
The one surefire thing LBJ knew was how to legislate. As the undisputed leader of the Senate, and master tactician in building consensus around legislation in the 1940s, 50s, and 60s, he could always find a "middle ground," a way to offer concessions without losing too much in terms of domestic policy objectives. In order to yield effective legislation in the Senate, which would eventually become law, LBJ would not be caught blind-sided losing too much to either the opposition politicians or in losing too much favor in the popularity polls taken of the general public.
Incrementalism, compromise, and consensus -- that is what LBJ the legislator knew best, in addition to some arm twisting now and then.
But, sadly, poor ole LBJ never fully realized that, especially in foreign affairs, bein' President means you ain't in the legislatin' role no more -- you're in the doggone decision makin' role. And incrementalism, compromise, and consensus is not always useful for a President in military matters. Instead, a firm policy decision is always useful.
The President decides policy objectives based on the advice and honest appraisals set forth by his advisors, and LBJ (bein' the President an' all) needed to decide and set policy -- especially in military affairs. Then, LBJ should have let the Pentagon and civilian advisors focus on strategy, and the guys in the trenches forge the tactics to get the policy objectives accomplished. With Vietnam, this never happened. The was no leader leading on Vietnam.
In fact, the insecure LBJ, in the unfamiliar world of military decision making, put off and pushed away his military advisors, and dodged the hard choices about Vietnam (as presented by the civilian staff allowed access to him). And the Joint Chiefs of Staff let him get away with it!
Even worse, both LBJ and McNamara learned during the Cuban Missile Crisis that the military advisors from the Pentagon were old fashioned, out of touch with cold war nuance, and (given the chance) would nuke the enemy back to the stone age (and take America there too in the process). Perhaps LBJ and McNamara "learned" too broad a lesson, that was not universally applicable. What they learned was "Who can trust those fellahs from the Pentagon?" But Vietnam was no Cuban Missile Crisis. Apples and oranges.
Instead of leading on all policy matters equally, as needed, LBJ focused much more intently on the noble domestic policy goals he clearly preferred.
Take, as an example, the Voting Rights Act, and other Civil Rights legislation (both in play along with immigration reform as part of the bigger Great Society programs competing with Vietnam for LBJ's attention). LBJ knew it was now or never to finally, FINALLY, settle the unresolved issues remaining from the Civil War that supposedly ended with a Union victory 100 years prior, in 1865. For LBJ, the Jim Crow South, and the rampant discrimination against black citizens and immigrants in the North, sure did not look like a Union victory to him.
Hmmm. Was the final settlement of the Civil War
(in law, and in fact) more important than the prolonged and honest focus required to avoid gradual escalation of American militarization of the Vietnamese conflict? Was it a huge error to distrust the Joint Chiefs of Staff and instead micromanage military tactics in Vietnam from the White House with only civilian advisors (read: "McNamara"), with no clear military policy objectives? Should the Joint Chiefs have been so passive (they knew they were on a sinking ship, and seemed too compliant in acquiesce in the shenanigans of MBA McNamara)? Is war planning by MBA analysis a good thing?
Similarly, would it have been wise, as a tactic, to rearrange the deck chairs on the Titanic to somehow advance the policy decision to create an unsinkable Titanic, and keep it from sinking?
How did LBJ allow our country, from November 1963 to the summer of 1965, to gradually, mindlessly, and shamefully hit the iceberg of Americanization of a local Vietnamese domestic "spat?" How did he permit the senseless sinking of our American Titanic, with all the resulting needless deaths and wasted billions of dollars, which simply ended in disaster?
H.R. Master's scholarly, rationally, and expertly composed review and summary of the expansive written military record (memos, policy papers, meeting notes, etc) will answer these questions. LBJ, with the best of intentions, and with the advisors he manipulated and duped, and who duped him in return, all wove a web of lies that entrapped the Joint Chiefs, the American public, and world leaders. The web of lies was born of arrogance, paranoia, and based on domestic political concerns for the Great Society legislation. Domestic political concerns of historical proportions squelched the inevitable conclusion that the Vietnam conflict would end in disaster.
The military did not lose on the Battlefield in Vietnam. Simply put, regardless of the reasons (and however noble the pursuit of the Civil Rights legislation may have been), the dereliction of duty, of our national leaders, both military and civilian, in Washington DC, was fatal for our soldiers in uniform. This dereliction of duty lost the war in Vietnam before it began -- before it became an American War handed to us by South Vietnam, which was unwilling to prosecute, and incapable of prosecuting, their own cause against the North Vietnamese in the first place.
