Successful coping with either external or internal pressures requires selective change. That’s as true of nations as of individuals. The key word here is “selective.” It’s neither possible nor desirable for individuals or nations to change completely, and to discard everything of their former identities. The challenge, for nations as for individuals in crisis, is to figure out which parts of their identities are already functioning well and don’t need changing, and which parts are no longer working and do need change.
