I don’t know any other way to interpret these statements, other than to say that Iran will attack Israel with nuclear weapons at the earliest possibility (emphasis added):

The president of Iran again lashed out at Israel on Friday and said it was “heading toward annihilation,” just days after Tehran raised fears about its nuclear activities by saying it successfully enriched uranium for the first time.

[...]

“Like it or not, the Zionist regime is heading toward annihilation,” [Iranian president Mahmoud] Ahmadinejad said at the opening of a conference in support of the Palestinians. “The Zionist regime is a rotten, dried tree that will be eliminated by one storm.”

Ahmadinejad provoked a world outcry in October when he said Israel should be “wiped off the map.”

[...]

On Tuesday, Ahmadinejad announced that Iran had successfully enriched uranium using a battery of 164 centrifuges, a significant step toward the large-scale production of enriched uranium required for either fueling nuclear reactors or making nuclear weapons.

For the last few years, peace-at-all-costs advocates have argued that there is no justification for pre-emptive war. They claim that talk and diplomacy can solve all world crises, and that we should put our trust in the United Nations to do just that.

If ever there were a time for the U.N. worshippers to prove that their cherished institution is of any use at all, this is it. Put up or shut up. Solve this problem. The world needs it.
