Four or five years ago, a suspicious event occurred in New York. A building collapsed and they said that 3,000 people had been killed but never published their names.
The AP article goes on to observe:
On the last anniversary of the attacks, the names of 2,750 victims killed in New York were read aloud at a memorial ceremony.
That list of victims is public information and widely available, a simple Google search turned up this site where the names are available and I daresay the New York Times has published a similar list.
I wonder how widely Ahmadinejad is believed? There are two ways to view what he said: he is lying or delusional.
One is reminded of former Senator Bob Kerrey's characterization of Bill Clinton as "an uncommonly good liar." Taken to task for criticizing a fellow Democrat, Kerrey protested that in fact he meant it as a compliment, adding that fluent lying is a very useful skill for a politician. Ahmadinejad is a certainly a politician, perhaps he believes he has this skill. Humorists say you can tell if politicians are lying...their lips are moving.
Alternatively, he is delusional, out of touch with reality. Not a nice thought about someone who will have nuclear weapons at his disposal one day soon. Ahmadinejad talks like the Muslim equivalent of our Christian end times enthusiasts. What you don't want to hear from such folks when they control a nuke is "bring it on."
