If any journalist should bother to view these segments from four extraordinary interviews of three presidents and one would-be president, they might notice they have two things in common. They are all with the same television talk show host, and no one gives a straight answer. Why is that? Why are the most powerful politicians of the past quarter century unable or unwilling to speak clearly on an issue of huge global implications? Jimmy Kimmel is a fine entertainer, but not a journalist. Where is The Times, the Washington Post, the New York Times? When will the American public tire of being treated like children, or worse, potted plants?
