Morton's review:

Burnham began his career in political activism as a Trotskyite communist and became a very committed anti-communist.  Like Buckley,  Burnham, in the '60s and '70s particularly, provided intellectual fortification for the conservative movement.

First published in the early sixties, Suicide of the West is a withering indictment of liberalism.  Far from serving as a bulwark against communism, liberalism, Burnham shows, is the ideology of Western suicide, communism in its preliminary stage.  Though Soviet communism has collapsed, liberalism remains, and as long as it does, Suicide of the West should be read by conservatives.
