It’s time for Americans to wake up to a fundamental reality: the continued unity of the United States of America cannot be guaranteed. At this moment in history, there is not a single important cultural, religious, political, or social force that is pulling Americans together more than it is pushing us apart. We cannot assume that a continent-sized, multi-ethnic, multi-faith democracy can remain united forever, and it will not remain united if our political class cannot and will not adapt to an increasingly diverse and divided American public.
