A book review about war?

Mark Steyn offers a book review that struck me apropos as a reality check.

Before the white man came? War

The subtitle says pages: "We've deluded ourselves into believing in the myth of the noble and peaceful primitive"

"Forgetfulness occurs when those who have been long inured to civilized order can no longer remember a time in which they had to wonder whether their crops would grow to maturity without being stolen or their children sold into slavery by a victorious foe. . . . That, before 9/11, was what had happened to us. The very concept of the enemy had been banished from our moral and political vocabulary."
