Robert Kagan knows very well why Sen. Paul doesn’t take a more unconventional line on Iran policy. We have seen it on display for the last seven weeks in the panic over Hagel’s nomination and we have seen it over the last six years as Sen. Paul’s father has been written off as a “fringe” figure because he takes exactly the position on Iran that Kagan describes. Obviously, Kagan isn’t interested in having a “true dissenter” in the debate, and he hates them when they appear.
