I would say that the one incredible thing that Karachi has going for it is the unabated supply of new migrants that pour into it day after day. It could be a poor factory worker who simply wants a job, it could be an ambitious guy coming for an education - they all add hope and vibrancy to the city. Now, this is not something that is generally taken as positive in Karachi. But the hope is that the migration that comes into the city replenishes its stores of resilience and energy.

When I choose the picture of the cover of the book 'Instant City: Life and Death in Karachi', I thought, gosh, many people in Karachi may not like this image; I'm representing the city as a burning bus. But to the contrary, they loved it, because that is people's understanding of their own city, of going on with life no matter what.

People don't know where they stand and what they're going to lose, and that makes things uncertain. The political parties try to meld people together, but then that becomes a problem. There are parallels here, to American cities, which, in the '80s, with massive rural to urban migration, saw incredible amounts of violence.

Identity liberalism, as I understand it, is expressive rather than persuasive.
