Bacevich: The Limits of Power (from 'The Big pictue')'. Flavour of the opinions (with which I am much in agreement) from this one quote:
"BILL MOYERS: Here is one of those neon sentences. Quote, "The pursuit of freedom, as defined in an age of consumerism, has induced a condition of dependence on imported goods, on imported oil, and on credit. The chief desire of the American people," you write, "is that nothing should disrupt their access to these goods, that oil, and that credit. The chief aim of the U.S. government is to satisfy that desire, which it does in part of through the distribution of largesse here at home, and in part through the pursuit of imperial ambitions abroad." In other words, you're saying that our foreign policy is the result of a dependence on consumer goods and credit."
There are several articles by Andrew Bacevich in Tomdispatch
