Why doesn't Ahmadinejad do his own clarifying?

The top ten things you didn't know about Iran

Belief: But didn't President Mahmoud Ahmadinejad threaten to "wipe Israel off the map?" 

Reality: President Mahmoud Ahmadinejad did quote Ayatollah Khomeini to the effect that "this Occupation regime over Jerusalem must vanish from the page of time" (in rezhim-e eshghalgar-i Qods bayad as safheh-e ruzgar mahv shavad). This was not a pledge to roll tanks and invade or to launch missiles, however. It is the expression of a hope that the regime will collapse, just as the Soviet Union did. It is not a threat to kill anyone at all.

That Juan Cole's lame attempt at a "reality" — (which really doesn't help much as "this Occupation regime over Jerusalem must vanish from the page of time" still sounds pretty threatening.)

My question is why doesn't Ahmadinejad offer his own clarification — a benign and reassuring one? Wouldn't take but about 30 seconds and he could clear up whatever dispute there may be.

(Btw, criticism of Cole is not to support neo-con irrational perspective on talking with thine enemies. Remember what Godfather Don Corleone said: "Keep your friends close and your enemies closer.")

Update: Ahmadinejad's own ethnicity is not really relevant to this post.
