What I don't get is what people like Ahmadinejad actually want from the Israelis...?

That they pack up and leave (where??)
That they commit mass suicide...?
That they scrap their army and wait to be invaded and killed?
That they all convert to Islam (would they be left alone if they did?)

And who wrote that virus that attacked the Iranian nuclear plant? The US or Israel?

I have no issue at all with Iran having nukes - just as long as it's not specifically for a preemptive strike against Israel. For all its faults... I think Israel has a right to exist as a Jewish state and I hope I don't annoy anyone here too much by saying that.

The other thing i don't quite get is: Why does Iran even care about Israel? Iranians are not Arabs, Israel is nowhere near Iranian territory and it has no interest in invading Iran. So why exactly is it such a big deal to Iran? I think the rhetoric from the Iranian leadership about Israel is very offputting.

And about invasion of Iran:

Anyone who is stupid enough to invade Afghanistan... and greedy enough to invade Iraq... (after having previously supported the exact regimes that they later turned against) .... would probably drool at the thought at "liberating" Iran (including its oil..) .
Unless the American people come to their senses and do something about their rotten politicians I think all the signs are there that thats exactly what they'd like to do after they are done in Iraq and Afghanistan.
