Late last year, the writer, polemicist and fierce proponent of the US-led invasion of Iraq Christopher Hitchens attempted, in a piece for the online magazine Slate, to draw a distinction between what he called techniques of "extreme interrogation" and "outright torture".
From this, his foes inferred that since it was Hitchens' belief that America did not stoop to the latter, the practice of waterboarding - known to be perpetrated by US forces against certain "high-value clients" in Iraq and elsewhere - must fall under the former heading.
