For her book, Michelle didn't randomly pick a historical subject that happened to greatly interest her. She chose the World War II internment issue, I think, because she believes our national perception of it shapes our current attitude toward important security measures in the War on Terror.
Michelle is one of the leading proponents of controlling our borders and national security in general. She has been particularly troubled by the willingness of some groups to subordinate our national security to often-overblown competing interests.
It's not that civil liberties aren't highly important to Michelle, but she sees their invocation by "Chicken Little Civil Libertarians" as sometimes needlessly impeding our national security, without which we will have no freedom at all.
As Michelle says, most of the civil libertarians aren't really interested in balancing civil liberties and national security. To them, "civil liberties always and at all times outweigh national security, and anybody who doesn't think so is a free speech-hating, Bill of Rights-trampling, immigrant-bashing tyrant."
Her main thesis is that evacuation and relocation of ethnic Japanese from the West Coast, and also of enemy aliens of any ethnicity during World War II, was not a despicable, irrational, xenophobic act driven by the racism or "wartime hysteria" of American leaders. Instead, there was a strong rational basis for internment, based on mountains of information available to our government indicating that a genuine security risk existed.
Michelle describes how history revisionism against internment has made the subject "sacrosanct" and beyond debate. But she notes that she has no vested interest in either side of the argument as so many who have written on the subject do.
She first corrects some of the commonly held myths about the "internment," including that it only involved Japanese people -- "Enemy aliens of European ancestry made up nearly half of the total internee population." She also clarifies that ethnic Japanese living outside prescribed military zones were not affected by the "internment" order -- President Roosevelt's Executive Order 9066.
