Norman Spinrad lives just up the hill from me, but we don't see each other nearly as often as we'd like. Writing can be a lonely business.
Spinrad was once considered a "new wave" writer, but since I haven't any notion of what that means, I can't comment. I do know that he pays attention to character as well as technical detail, but then, so do a lot of writers who aren't thought "new wave" at all. One thing is certain. He can tell stories that you'll remember a while.
In conventional thought, Democracies are preferable to Empires, because they are more humane and ethical, and more likely to adhere to the rule of law. The facts are different. Polities conventionally described as Republics have had imperial ambitions, and have often enforced their imperial rule over others. The Athenians converted from Republic to Democracy, but continued to act as colonial masters over their former allies in the Aegean. And as C. Northcote Parkinson points out, they enforced their rule with a cynical ferocity matched only by the most ruthless of dictators.
On one occasion, Mytilene wished to withdraw from the alliance and cease paying tribute to Athens. The Athenians blockaded the city and brought about its surrender, after which Cleon got the popular assembly to decree that the entire military-age population of Mytilene should be massacred, and everyone else sold into slavery. A galley was dispatched to deliver the order to the Athenian military commander at Mytilene.
The issue was debated again the next day. When Diodotus called for mercy, Cleon demanded justice: he warned the Athenians that the maintenance of empire demanded that the subjects be kept in a constant state of fear, and the empire would pass away if the Athenians were guided by compassion.
The moderates won, and another ship was dispatched to rescind the orders of the first. On that happy occasion, the first ship, bearing the dreadful news, was slow, while the second was rowed by men eager to arrive on time.
Athens was hardly the last state, republic or empire, to sacrifice principle to expediency. For all the power of the state, though, the decrees of Republic and Empire alike must be carried out by men.
