America Alone by Mark Steyn
Europe, laments Steyn, is almost certainly a goner. The future, if the West has one, belongs to America alone—with maybe its cousins in brave Australia. But America can survive, prosper, and defend its freedom only if it continues to believe in itself, in the sturdier virtues of self-reliance (not government), in the centrality of family, and in the conviction that our country really is the world’s last best hope.

Steyn argues that, contra the liberal cultural relativists, America should proclaim the obvious: we do have a better government, religion, and culture than our enemies, and we should spread America’s influence around the world—for our own sake as well as theirs.
