It's five years since the conflict in southern Lebanon. What lessons do you draw now?
It was the first war in Israel's history that ended without it achieving a clear victory. The consensus is that, on the one hand, Israel could not have stopped the Hezbollah rocket attacks without launching a ground invasion but, on the other, it could not have launched a ground invasion without incurring military casualties, which Israeli society will not accept. So far, Israel has not figured a way out of this dilemma.

As a measure of success, Israel says the border with Lebanon is now quiet. Do you agree?
The Israel-Lebanon border is now quieter than ever before. It is the result of a local version of the MAD [mutually assured destruction] doctrine: neither side wants to risk its home front coming under attack by the other side. But, for Israel, such a status quo is unacceptable. Its strategic doctrine is premised on being free to unleash its military might when and where it chooses. That Hezbollah has imposed unacceptable restraints signals that the situation is unstable and will almost certainly culminate in another war, launched - or provoked - by Israel.

Does Israel want peace with the Palestinians?
Everybody wants peace. That's a truism. There is no point in accomplishing through war what you can accomplish through peace. The question is: peace on what terms? Then you start getting to the heart of the problem. Israel and Palestine is probably the least complex problem in the world today. Everybody agrees what the final-status questions are - borders, Jerusalem, settlements and refugees.

But isn't the devil in the detail?
There's no devil whatsoever in the detail.

Hamas fires mortars on to and kills civilians. Why would Israel do business with terrorists?
I'm not even going to engage in this kind of game: are Hamas terrorists? OK, I'll just concede it; let's not waste any more time. So, then, let's compare the record. Israel launches an attack on Gaza. As the Israeli ministry of foreign affairs put it, "Hamas was careful to respect the [2008] ceasefire," and it was Israel that broke the ceasefire on 4 November 2008. If Israel were really concerned about mortars and rockets, it wouldn't have broken the ceasefire.

Do you think the unity deal recently struck between Hamas and Fatah will last?
If the Palestinian Authority decides to go the route of UN recognition, it needs the unity deal because the international community has made that a precondition. If it decides to resume the "peace process", it doesn't need Hamas, and will have to ditch it because the US and Israel will not negotiate with Hamas. In private, Israeli diplomats will tell you that they don't believe Mahmoud Abbas has the political strength to deliver peace. You don't need political strength. Because all you have to do is present the terms for a settlement and then you can have a national referendum. If he concedes everything to Israel, then he'll need political strength.

In your view, Israel has appropriated the Holocaust. Could a non-Jew have said that?
There is no way a non-Jew could say what I did in The Holocaust Industry without being labelled a Holocaust denier. I am labelled a Holocaust denier, too. Nobody disputes that my parents were in the Warsaw Ghetto from 1939 to 1943. If I were denying the Holocaust, I would have to be certifiably insane.

Your parents went to the US after the war. Did they consider going to Israel?
My mother used to joke sometimes because the Judenräte, the Jewish councils, played such a filthy role during the Nazi Holocaust that, when asked "Why didn't you go to Israel?", she said: "I'd had enough with Jewish leaders."

Is there anything you'd like to forget?
I did a lot of wrong things, morally wrong, personally wrong. I made major political errors in my life. But I don't want to forget them, because they put me on notice.

Is there a plan?
It's too late to speak of a plan - I'm 57 years old.

Do you vote?
I don't. I understand the rational argument for voting, but . . . I can't stand these people. I could never vote for Barack Obama.

Why not?
Because I think it's all hollow clichés and platitudes. I can't bear it. He's a complete fraud.

He's brought health care to millions.
I'm unemployed and one of those 40 million Americans who has no health insurance, so I know all about insurance that I can't afford.

Are we all doomed?
I don't think in such big terms.

Do you believe in God?
No. When I was a young man, my mother said to me, "You can't be a communist without being a militant atheist." So I had to be a militant atheist because I wanted to be a communist.
