It was unthinkable to LBJ (or probably his wife) to be the first
US President to admit defeat in any war. Hell, even his successor
didn't admit defeat, but rather declared victory and went home. LBJ
in essence, resigned the presidency over his inability to resolve
the Viet Nam issue, and this in spite of having had more success
on thorny domestic issues since FDR.

He had terrible advice, from guys like Westmoreland and McNamara,
who were supposed to be the best and brightest but who were fighting
a different war in a different place than the one which was before
them, and who were too weak to give the advice to cut our losses.

Hmmm---- this begins to look all too familiar.
