I went to a Federalist Society speaking engagement today that featured John Yoo, a law professor at UC Berkeley (Boalt Hall) and former law clerk to Justice Clarence Thomas. From 2001 to 2003, Professor Yoo served as a deputy assistant attorney general in the U.S. Department of Justice.
As you might well be able to guess, the main topic of Professor Yoo's talk was the war on terror, and in particular, the national security policies of the Bush Administration (e.g., NSA wiretapping, coercive interrogation of terrorists, the Patriot Act). For all the handwringing that "civil libertarians" have been engaging in over these policies, Professor Yoo persuasively illustrated that not only does the administration have precedence on its side, none of what is going on now is nearly as "drastic" as what past presidents have done in previous wars. Roosevelt, for example, had ordered the monitoring of all forms of domestic communications a full year and a half before the U.S.'s formal entry into World War II. The Republic not only survived this seemingly imperial act, civil liberties would actually be expanded after the war concluded.
What I really found interesting about Professor Yoo is his willingness to publicly defend the Bush Administration's national security and war policies even when the administration itself does not seem all that interested in doing so. Indeed, this is the one major criticism that Professor Yoo has of the administration (he was especially critical of former Sec. of State Colin Powell and current Sec. of State Condoleeza Rice).
As a side note, I got to speak with Professor Yoo a little bit before he gave his lecture, and he informed that his old boss, Justice Thomas, will be releasing a book of his memoirs sometime this summer. In case you're wondering, the book is expected to address the whole Anita Hill affair.
