Rich:

[You] I shall, as Derb would say, be debating Katrina vanden Heuvel …

[Me] I am not sure which part is as I would say it. The “shall,” perhaps, which notoriously switches places with “will” not only when crossing the Atlantic (airline pilots should announce the switching-point over the cabin PA system), but even when crossing the Scottish border. One is what Fowler (Modern English Usage) calls the “plain” sense, the other “coloured” (i.e. with intentionality or obligation) . . . though it’s different in different persons (first, second, third), and tense and mood throw two more spanners (that’s wrenches) in the works . . . Wilson Follett (Mosern American Usage) says that “most of the advice on the future and the conditional in English (to say nothing of the other uses of these auxiliaries) has been given in a tone of despair.”

That’s all by the by (“usually so written, though the second by is a noun” — Fowler). The main point of this post is to alert you to the fact that Katrina vanden Heuvel is a witch. In fact, if you saw the movie Men In Black II, you should need no further clues. Be on your guard!
