In characteristically persuasive style, Amy Chua argues that America must rediscover a national identity that transcends our political tribes. We?ve had enough false slogans of unity, which are just another form of divisiveness. It is time for a more difficult unity that acknowledges the reality of group differences and fights the deep inequities that divide us. Chua offers a bold new prescription for reversing our foreign policy failures and overcoming our destructive political tribalism at home.
