I'd like to come back to the West eventually. In the end abroad I am always a stranger, active politics in particular is not accessible to me and although people are generous, I can never be on the inside of a culture that relies a great deal on the private space and the family.

If democracy is to be rebuilt … it is necessary not just for the public to learn to trust their politicians, but for the politicians to learn to trust the public.

The question shouldn't be what we ought to do, but what we can do.

Change can only come from local citizens and politicians - it cannot be imposed by well-meaning foreigners - not least because a society like Afghanistan or Iraq is suspicious of outsiders and often resistant to change. I am not going to get drawn into the ethics of intervening in other countries. My concern is the practical question. Can you actually achieve change in this way? My guess is we can stop wars sometimes as in the Balkans and topple regimes - but that the other stuff - such as corruption is not within our power to effect and alter.

I do a lot of work with policymakers, but how much effect am I having? It’s like they’re coming in and saying to you, ‘I’m going to drive my car off a cliff. Should I or should I not wear a seatbelt?’ And you say, ‘I don’t think you should drive your car off the cliff.’ And they say, ‘No, no, that bit’s already been decided—the question is whether to wear a seatbelt.’ And you say, ‘Well, you might as well wear a seatbelt.’ And then they say, ‘We’ve consulted with policy expert Rory Stewart and he says . . . .’

I found incredible kindness, dignity and hospitality in both Iraq and Afghanistan - am only alive because of it - the most worthwhile lesson of a twenty month walk to these countries was a deepening appreciation of the kindness of strangers.

In the mountains, travelers were reduced to the speed of men on foot. Here, the ancient English sense of journey, 'a day's travel' (French journee), meant the same as the Old Persian word farsang, 'the distance a man could travel on foot in a day,' and the territory was in effect ungovernable.
