The national religion of the United States of America is nationalism. Its god is the flag. Its prayer is the pledge of allegiance.
The flag’s powers include those of life and death, powers formerly possessed by traditional religions. Its myths are built around the sacrifice of lives to protect against the evils outside the nation. Its heroes are soldiers who make such sacrifices based on unquestioning faith. A “Dream Act” that would give citizenship to those immigrants who kill or die for the flag embodies the deepest dreams of flag worship. Its high priest is the Commander in Chief. Its slaughter of infidels is not protection of a nation otherwise engaged, but an act that in itself completely constitutes the nation as it is understood by its devotees. If the nation stopped killing it would cease to be.
