Below are excerpts of Johnson's review which illuminate Wolin's "managed democracy" concept and summarize the relationships between imperialism, democracy and militarism.
The main objectives of managed democracy are to increase the profits of large corporations, dismantle the institutions of social democracy (Social Security, unions, welfare, public health services, public housing and so forth), and roll back the social and political ideals of the New Deal. Its primary tool is privatization. Managed democracy aims at the “selective abdication of governmental responsibility for the well-being of the citizenry” under cover of improving “efficiency” and cost-cutting.
...
One other subordinate task of managed democracy is to keep the citizenry preoccupied with peripheral and/or private conditions of human life so that they fail to focus on the widespread corruption and betrayal of the public trust.
...
Another elite tactic of managed democracy is to bore the electorate to such an extent that it gradually fails to pay any attention to politics.
...
Imperialism and democracy are, in Wolin’s terms, literally incompatible, and the ever greater resources devoted to imperialism mean that democracy will inevitably wither and die.
...
... Over the years, American political analysis has carefully tried to separate the military from imperialism, even though militarism is imperialism’s inescapable accompaniment. The military creates the empire in the first place and is indispensable to its defense, policing and expansion.
