Yeah it is- in fairness to LBJ though he inherited Viet Nam, and hated our involvement but felt he had no choice other than stay the course. The war didn't really become unpopular until Tet in 1968- until then most believed in the Domino theory and felt our involvement was necessary.
butter me! When Kennedy died there were ~16k US troops in Vietnam. President...even VP's that inherit the office... are supposed to make the tough decisions. For a guy that hated our involvement he sure as hell did nothing to reduce it. If there was ever a time to back away it was when Kennedy died.
Instead LB mushferbrains J decided to pour in US troops and run the war from the oval office. He and his brainless sidekick Robert
Strange McNamara sure were smarter than all them gol darn ole military men, weren't they? Nearly HALF a MILLION troops in-country by the end of 1967.
Sorry, Kennedy may have made a small error but LBJ blew it up into a gargantuan problem. VietNam was LBJ's war all the way. And it would simply be impossible for someone to even deliberately mismanage it to a greater degree than he and Bobby Strange did.
