This afternoon, Iranian President Mahmoud Ahmadinejad spoke by invitation at Columbia University. (See Gabriel Schoenfeld’s post here.) Ahmadinejad has made clear that he considers the U.S. and Iran to be mortal enemies, and that the victory of Iran in the struggle between them is divinely ordained. This is to say nothing of his intention to develop a nuclear bomb, his genocidal attitude toward Israel, his denial of the Holocaust, and his blatant anti-Semitism and hatred of Christianity. In March 2005, the noted legal scholar Andrew McCarthy addressed in COMMENTARY the question of how far American legal protections of speech should extend toward our nation’s declared Islamist enemies. In “Free Speech for Terrorists?” he concludes that the First Amendment is not now and never has been a suicide pact.
