The role of U.S. capitalists in cold war policy

[Walt Byars <wbyars@xxxxxxxxxxxx>]

Does anyone know of any good sources discussing (even ones mentioning it
as an aside work) the role of capitalists in supporting, facilitating, and
formulating U.S. cold war foreign policy, particularly when it comes to
military intervention and other sorts of opposition to leftist movements
in other countries. Also interested in direct, not merely circumstantial,
evidence of U.S. foreign policy in this era being used to support U.S.
business interests. A teacher of mine I was discussing this with conceded
that these policies did help U.S. capital, but claimed that for the most
part there wasn't evidence that this was their intent. I believe I've seen
quite a deal of such evidence, I just odn't remember the specific sources.
