Vietnam all over again?

From Politico's Glenn Thrush:

"California Dem Jane Harman, likes Obama's overall strategy, but says the reported 34,000 troop build up goes too far -- comparing it to (gulp) LBJ's failed Vietnam escalation: "...There are eerie echoes of Vietnam and the crucial 1965 memo to President Johnson in which National Security Adviser McGeorge Bundy wrote, ‘The situation... is deteriorating, and without new U.S. action defeat appears inevitable. There is still time to turn it around, but not much.’ Bundy turned out to be wrong, and I think a troop build-up as part of an otherwise careful and thoughtful strategy is also wrong.”
