I took my translation - "the regime occupying Jerusalem must vanish from the page of time" - from the indefatigable Professor Juan Cole's website where it has been for several weeks.
But it seems to be mainly thanks to the Guardian giving it prominence that the New York Times, which was one of the first papers to misquote Mahmoud Ahmadinejad, came out on Sunday with a defensive piece attempting to justify its reporter's original "wiped off the map" translation. (By the way, for Farsi speakers the original version is available here.)
Joining the "off the map" crowd is David Aaronovitch, a columnist on the Times (of London), who attacked my analysis yesterday. I won't waste time on him since his knowledge of Farsi is as minimal as that of his Latin. The poor man thinks the plural of casus belli is casi belli, unaware that casus is fourth declension with the plural casus (long u).
