LBJ put politics over everything else, including his country, his family, his mistress, and his illegitimate son. He had zero integrity, no ethics, and largely charted the course for the disastrous path this country has had since he gained congressional power. The grass grows well on his grave.
He is the first to intentionally cause the Military to lose.
Woodrow Wilson also went for a stalemate for WWI to end in an armistice. That was just time for the enemy to rearm and start again 20 years later.
......I think it is even worse than that. He, McNamara and Rusk strung out the Vietnam War and micro-managed it to the detriment of the grunts and the profit of the military industrial complex. I hate the sonofabitch for that because one of those marines killed was my best boyhood buddy. Then, he and Lady Broad (being nice) profited millions off contracts to large US construction companies. LBJ and Lady BRoad are a case study in corruption.
Now, along comes Obama and he and LBJ are roughly equal except that Obama hates his country. LBJ didn’t. He was all politics and money in his bank account!
