Entirely possible, but for a misquote, it's been reported everywhere. Some translate it as "the regime occupying Jerusalem must vanish from the page of time" (not sure that is any better for Israel) though:

Annan denounced his statements:

Or possibly, the translation was wrong all along?

>I don't know (didn't know) this guy. Reading a bit on that webpage, it is now clear to me that he is a true antisemite. Having said that, let's see whether we can do some useful things with what he says and what has happened in Teheran.

>1) He denies that the president of Iran has actually said that Israel will soon be wiped out. Indeed, this is what I have been reading in my newspaper, just this morning. The columnist who said this is a jew like me, not orthodox, not even a theist. He is a liberal, secular jew. Was he manipulating me and all others, or was he manipulated by his resources, or was he simply plain right? I guess it is important here to find out what the president really said.

>2) This David Duke claims that Iran has held this conference to underline that freedom of speech is very important. That implies that 'we' can from now on confront the Iranian government with this statement each time that they suppress people who criticize Iran. That's the positive side of this all.

>BTW, quite some time ago I sent a letter to the Iranian Embassy. Because they deny the Holocasut I asked them whether they can tell me where nearly 80 family members that we haven't seen since WWII live these days. Also I told them I was shocked when I realized that my father had been lying all those years. No answer received so far, not even a reply confirming they received it. I have decided to restart believing my father, because they didn't come with additional proof.
