if the way ahead is not clear, time is often the best editor of one's intentions.

If you look at the First World War, the Kaiser was actually, actively buying a lot of the armaments from Britain! in the years, in the run-up to the First World War. And I mean, there was a connection there. He was, indeed, Queen Victoria's grandson. You know, they were all related, all these royal families.

As Churchill said about the Great War, and he said this in about 1924, that it was the first war in which man realized that he could obliterate himself completely. If you consider the way the whole world was impacted, 18 million people worldwide died, and that is taking into account military and civilian deaths: 18 million people. And it was the whole world, if you will. You know, many of those trenches were dug by Chinese. There are photographs of Chinese looking like they just came from China, with their hats and so on, digging the trenches, right from the beginning.

It was Harry Patch, who was the last living World War I veteran; and by veteran I mean someone who actually fought in the war, he didn't just happen to be in the army at that time, in the Great War. And when the Iraq War started, he was interviewed, and they said, well what do you think of this? And he said, in a very sad voice, "Well, that's why my mates died. We thought we were going to end all that sort of thing."

What does anyone really know about the impetus to go to war? And so much is uncovered in hindsight. And there are aspects of even past wars that are only coming out now. Historians discover letters here, notes there, and look very carefully at different aspects of not only any conflict but any great historical event.

a question has the most power before we rush to answer it, when it is still making us think, still testing us.

Stay with the question. The more it troubles you, the more it has to teach you.
