Open, resilient, adaptive cities.

Our sages give a fascinating answer. The spies saw the walls around the cities and concluded that if the cities are strong, the people are strong. It's a natural assumption but the truth is the opposite. If cities are surrounded by high walls against invaders, that's a sign that the people are weak and afraid. It's when you see a city without walls, that you know the people who live there are strong.

And so it's proved to be. Historically it's been the countries most open to refugees that were the strongest: the Netherlands in the seventeenth century, Britain and America in the 18th and 19th. Why? Because refugees almost always give back more than they received. Helping others, we are helped.
