From the early 1960s to the mid-1980s - the era of military dictatorship when South Korea was rebuilding itself from a postwar economic basket case to a humming, modern nation - military schools were the track of choice for ambitious young men.

I like to take certain aspects of genre fiction and modify them in my own way. 'Your Republic Is Calling You' follows the form of a spy novel, but it leads readers into a world of Kafkaesque irrationality.

When I wrote 'Your Republic Is Calling You,' it was Franz Kafka's writing that I had most in mind, and James Joyce's 'Ulysses.' Entirely out of the blue, Kafka's characters receive an order to go somewhere, and when they try to comply, they never quite manage it. Ki-yong in 'Your Republic Is Calling You' is precisely that sort of character.

Of John Le Carre's books, I've only read 'The Spy Who Came In From The Cold,' and I haven't read anything by Graham Greene, but I've heard a great deal about how 'Your Republic Is Calling You' reminded English readers of those two writers. I don't really have any particular interest in Cold War spy novels.

It is not only the living who are killed in war.

My father was a Japanese prisoner of war, a survivor of the Thai-Burma Death Railway, built by a quarter of a million slave labourers in 1943. Between 100,000 and 200,000 died.

The contextual age means we're going to have to go to war on noise.

There are things about organized religion which I resent. Christ is revered as the Prince of Peace, but more blood has been shed in His name than any other figure in history. You show me one step forward in the name of religion, and I'll show you a hundred retrogressions.
