We have crossed the boundary that lies between Republic and Empire. If you ask when, the answer is that you cannot make a single stroke between day and night: the precise moment does not matter. There was no painted sign to say: ‘You are now entering Imperium.’ Yet it was a very old road and the voice of history was saying: ‘Whether you know it or not, the act of crossing may be irreversible.’ And now, not far ahead, is a sign that reads: ‘No U-turns.’
