I think wars, climate change, all that stuff is going to move people. And so I wanted to say, "What if the migration apocalypse occurs and it isn't an apocalypse at all?" Maybe we will still find ways to be happy and for our children and grandchildren to thrive and the world to move on.

Living in a place like Pakistan, very often you meet people who are migrating abroad. And sometimes you'll ask their parents, you know - you didn't try to stop them? Like, why didn't you say, don't go - I'll miss you? Stay with me. And, you know, people say, well, it's best for them. They have to go. And parents, you know, take on that sadness because they know it's better for their children if they leave.

It is not surprising that most Pakistanis do not support America's bombardment of Afghanistan. The Afghans are neighbours on the brink of starvation and devastated by war. America has shown itself to be untrustworthy, a superpower that uses its values as a scabbard for its sword.

The gun of the father is always the undoing of the son.

And also I think the rise of other, you could say, destinations for international jihadis mean that Pakistan isn't necessarily the place where people from all over the world who want to engage in these activities gravitate to. They're going now to places like Syria or Yemen Libya, elsewhere.

I feel engaged with young people in Pakistan. But that said, it's still a small minority that reads novels, literary fiction. But it isn't necessarily a small minority of the wealthy elite in the city of Lahore. It can often be and I often do meet at literary festivals students who've ridden a bus 12 hours from a very small town just to hear some of their favorite writers come and speak.

I think massive migration is inevitable. As sea levels rise, as climate change happens, as fertile fields become arid, as wars are fought, people are going to move. They always have.
