"all in 5 square kilometres"

From a conversation with a Gazan (who apparently follows this blog) that I had a few days ago, that seems to be stuck in my head:

"Gaza is not like the West Bank - in the West Bank, the Israelis can come into a town in a Jeep, with maybe 3 or 4 soldiers even walking along, arrest whoever they're interested in, and then leave. Nobody does anything about it. They would never dare try that in Gaza. Gaza is too well-armed. There are guns everywhere. The Gazans would fight. . .

". . . I was talking to an uncle of mine, and he said 'You know what? I've spent my whole life in 5 square kilometers. I was born, went to school, got married, got a job, all in 5 square kilometers. I've never left.' You have to wonder what that does to the society."
