Were Cheney/Halliburton as Corrupt as LBJ/RMN were in Vietnam?

I recently had a discussion with someone who claimed that the Iraq War was bungled through corruption by US government outsourced responsibilities that companies like Halliburton infamously made much money off of. I recall in my Vietnam years that Pacific Architecture & Engineering [PA & E] had a large interest in the company held by Lady Bird Johnson, a fact which got little or no press coverage at the time. PA & E and another Texas firm, Brown & Root, got huge contracts to build bases at Hoa Binh and Nha Trang in Vietnam, with nary a peep from the MSM of the time, the Cronkites and others who were such moral heroes, as E.R. Murrow was supposed to have been.

After RMN won the election in '68, Dem contributors like Bucyrus-Erie and such were replaced by Republican contributors like P&H, for example, but the largest share of the contractual booty had been amassed by the LBJ consortium.

It's worthy of interest that Robert Caro has interviewed every one of LBJ's inner circle except one, a little Baptist preacher named Bill Moyers, who inexplicably won't talk to Caro.

Could the reason be that Caro has a few skeletons in Moyers' relationship with LBJ that the phony PBS "guru" doesn't want to confront. Besides being arrested for DUI, perhaps Moyers has other reasons for not being interviewed by Caro.

Not that the MSM would ever abandon one of its favorite mantras, the evils of Republic corporate malfeasance.
