There was a time, long ago, when Americans pretended to believe in things—freedom, democracy, justice, the idea that if some leering despot charged across a border with guns blazing, it was our solemn duty to stand in his way and give him a good thrashing. There was a time when this country, for all its hypocrisies, at least had the good manners to keep them partially concealed beneath a lace doily of moral justification.

That time is gone.
