Empire or Republic?

Please read this article in current NYRB by Tony Judt. Here's a taste:

Historians and pundits who leap aboard the bandwagon of American Empire have forgotten a little too quickly that for an empire to be born, a republic has first to die. In the longer run no country can expect to behave imperially—brutally, contemptuously, illegally—abroad while preserving republican values at home. For it is a mistake to suppose that institutions alone will save a republic from the abuses of power to which empire inevitably leads. It is not institutions that make or break republics, it is men. And in the United States today, the men (and women) of the country's political class have failed. Congress appears helpless to impede the concentration of power in the executive branch; indeed, with few exceptions it has contributed actively and even enthusiastically to the process.

For there is a precedent in modern Western history for a country whose leader exploits national humiliation and fear to restrict public freedoms; for a government that makes permanent war as a tool of state policy and arranges for the torture of its political enemies; for a ruling class that pursues divisive social goals under the guise of national "values"; for a culture that asserts its unique destiny and superiority and that worships military prowess; for a political system in which the dominant party manipulates procedural rules and threatens to change the law in order to get its own way; where journalists are intimidated into confessing their errors and made to do public penance. Europeans in particular have experienced such a regime in the recent past and they have a word for it. That word is not "democracy."

The cost of empire: it requires its citizens to adopt humanity's worse instincts at the expense of its best. Which is precisely the political methodology of Bushco.
