Generals gathered in their masses
Just like witches at black masses
Evil minds that plot destruction
Sorcerers of deaths construction

Lets be real.

One, Israel is always upgrading and testing these new upgrades.

Two, clearly it is a response to the TWO recent missell tests.

Three, I think this one was actually for local Israeli consumption.
Sort of a reassuring that they are safe with all the rhetoric flying.
Basically, we can shoot down all those big new shinny missiles Iran has (offensive).

And that's the "slight little problem" with the Israeli Regime

Even if Iran and an hypothetic Arab coalition were to "wipe Israel off the map"

Wheter you think Ahmadinejad was talking only about the Regime or the whole people

Let's say you have the bulk of the 1st Arab Army closing in on Tel Aviv, Clearly for Israel; the War Is Lost, Even the US starts withdrawing their support

What are you to do? Hell... Bring em down with you

They will order the launch of their Strategic Missiles

Even if only a few are able to get off the ground, with the Wind and the Sand, the whole middle east will be contaminated for the next Century or so

Victory would have a bitter Taste wouldn't it?
