The interventionist monopoly on the leadership of the two state-supported major parties isn’t the only enabling factor involved in ramping up the Afghan war. There is also the rising power of the imperial class to contend with – that is, the growing economic and political clout wielded by sectors of the U.S. economy dependent on military contracts and the direct links between lawmakers and "private" companies that profit from war. A particularly brazen example of the latter is Sen. Dianne Feinstein, Democrat of California and formerly the mayor of what is generally regarded as the most liberal city in the United States.
All congressional representatives should have their wealth put into a blind trust before they ever take the oath of office, and not have any control over it until they leave.
Of course, that will happen when pigs fly.
But if, as a congressional representative, you or your spouse are making money, hand over fist through military contracts, you will see absolutely no reason for these wars to end.
