See the enemy and his motivations clearly and do not dismiss them.

Here is a book review that is worth reading:
Victor Hanson on Thornton

The reviewer, Victor Davis Hanson is a Senior Fellow at the Hoover Institution, Stanford University , a Professor Emeritus at California University , Fresno , and a nationally syndicated columnist for Tribune Media Services.

I should point out that if you are a flaming liberal, Hanson's writings may arouse your passionate anger. It appears that Bruce Thornton, the author of the book, is a conservative as well. They seem to expose the kind of facts that make liberals cringe.

But don't make the mistake of dismissing Professor Hanson as a "right-wing fanatic." Close examination will show he is nearer to the middle road than your first impressions may indicate. For example, he advocates "some sort of earned citizenship for most hardworking illegal aliens," and objects, on both practical and ethical grounds, to mass deportations.
