I've been reading America's Secular Challenge by NYU professor and president of the Hudson Institute Herb London. The book is essentially an extended essay about how elite, left-wing secularism undercuts America's traditional strengths of patriotism and religious faith during a time when the nation can ill afford it. The assault on public religion and love of country comes in a period when America faces enemies who have no such crisis of identity and lack the degree of doubt that leaves us in semi-paralysis.
The best compliment I can pay the book (by a Jewish social critic) is that it reminds me of the outstanding work of John Courtenay Murray (the great Catholic church and state scholar) who wrote:
And if this country is to be overthrown from within or without, I would suggest that it will not be overthrown by Communism. It will be overthrown because it will have made an impossible experiment. It will have undertaken to establish a technological order of most marvelous intricacy, which will have been constructed and will operate without relations to true political ends: and this technological order will hang, as it were, suspended over a moral confusion; and this moral confusion will itself be suspended over a spiritual vacuum.
