The key word is, of course, "Aids". Throughout the long article there is no trace of proof for this allegation. The reporters quote "sources in the Israeli security establishment". They also quote Israeli doctors "who heard from French doctors" - an original method for medical diagnosis. A respected Israeli professor even found conclusive proof: it was not published that Arafat had undergone an Aids test. True, a Tunisian medical team did test him in Ramallah and the result was negative, but who would believe Arabs?

Haaretz knows, of course, how to protect itself. Somewhere in the article, far away from the sensational headline, there appear the nine words: "The possibility that Arafat had Aids is not high". So Haaretz is alright. In army parlance, its ass is covered. By comparison, the New York Times, which published a similar story on the same day, treated the Aids allegation with contempt.

There is a very simple proof for the spuriousness of the allegation: if it had even the most tenuous basis in fact, the huge propaganda apparatus of the Israeli government and the Jewish establishment throughout the world would have trumpeted it from the rooftops, instead of waiting for 10 months. But, as matter of fact, there is no evidence whatsoever. More than that, the writers themselves are compelled to admit that Arafat's symptoms are completely incompatible with the picture of Aids.

So what did he die of?

Since taking part in his tumultuous funeral in Ramallah, I have abstained from giving my opinion on the cause of his death. I am not a doctor, and my dozens of years as editor of an investigative news magazine have taught me not to voice allegations which I am unable to prove in court.

But, since now all dikes have been breached, I am prepared to say what is on my mind: from the first moment, I was sure that Arafat had been poisoned.

Most of the doctors interviewed by Haaretz testified that the symptoms point towards poisoning, and, in fact, are incompatible with any other cause. The report of the French doctors, who treated Arafat during the last two weeks of his life, states that no known cause for his death was discovered. True, the tests did not find any traces of poison in his body - but the tests were conducted only for the usual poisons. It is no secret that many intelligence services in the world have developed poisons that cannot be detected at all, or whose traces disappear in a very short time.

Some years ago, Israeli agents poisoned the Hamas chief Khaled Mash'al with a slight prick in a main street of Amman. His life was saved only because King Hussein demanded that Israel immediately provide the antidote. (As a further indemnity, Binyamin Netanyahu agreed to the release from prison of another Hamas chief, Sheik Ahmed Yassin, who was assassinated several years after his return to Gaza by more conventional means - an airborne missile.)

In the absence of symptoms of any known disease, and since clear indications of poisoning were present, the highest probability is that Yasser Arafat was indeed poisoned while having dinner four hours before the first symptoms appeared.

I can testify that the security arrangements around the Ra'is were very lax. At each of my dozens of meetings with him in different countries I was always amazed at the ease with which a potential assassin could have done his job. Protection was always casual, especially compared to the way Israeli Prime Ministers are guarded. He often had his meals in the company of strangers, he embraced his visitors. Associates report that he frequently accepted sweets from strangers and also took medicines from visitors, swallowing them on the spot. After surviving dozens of assassination attempts, and even an airplane accident, he had come to adopt a fatalistic attitude, "it's all in the hands of Allah". I think that in his heart of hearts he really believed that Allah would preserve him until the completion of his historic mission.

If he was poisoned - by whom was he poisoned?

First suspicion falls, of course, on the Israeli security establishment. Indeed, Ariel Sharon declared on several occasions that he intended to kill him. The subject came up in cabinet meetings. Twice during the last years my friends and I were so convinced that this was imminent, that we went to the Mukata'ah in Ramallah to serve as a "human shield" for him. We were convinced that the murder of Arafat would cause much harm to Israel. In one of his interviews, Sharon stated that our presence there had prevented his liquidation.

Truth is that Sharon abstained from killing Arafat mostly because the Americans forbade it. They were afraid that the murder would arouse a huge storm in the Arab world and exacerbate anti-American terrorism. But this interdiction may have applied only to an overt act.

The Mash'al affair proves that the Israeli intelligence services have the means to poison people without leaving any trace. The poisoning was discovered only because the perpetrators were caught in flagrante.

However, a probability, high as it may be, is not proof. At the moment, there is no proof that Arafat was indeed poisoned by the Israeli services.

But if not the Israelis, who? The US intelligence services also have the necessary capabilities. President Bush never hid his hatred for Arafat, an obstinate leader who did not submit to his dictates. He was quick to embrace Mahmoud Abbas. Even now, American emissaries who visit the Mukata'ah pointedly abstain from putting wreaths on the grave of the Ra'is in the courtyard.

But American interests, too, do not constitute proof. One can think of several other suspects, even in the Arab world.

Did Arafat's death benefit Sharon?

On the face of it, no. As long as Arafat was alive, American support for Israel was unlimited. But since his death, President Bush has been going out of his way to support his successor. The dismal American debacle in Iraq compels Bush to look for achievements elsewhere in the "Broader Middle East". He presents Mahmoud Abbas as a symbol of the new winds blowing through the Arab and Muslim world as a result of American policy. In order to convince the Palestinian public to support Abbas, Bush is putting pressure on Sharon of a new sort. Perhaps Sharon is secretly longing for the good old days of Arafat, when life was simple and an enemy dressed the part.

But a person who wants - as Sharon surely does - to break the Palestinian people into pieces and prevent at any cost the establishment of a viable State of Palestine, can only be happy with the demise of Arafat, who united the entire Palestinian people. He had the moral authority to impose order, and he enforced it by empathy and force, human wisdom and tricks, threats and seduction.

There are many people in Israel who hoped that without him the Palestinian society would break apart, that anarchy would destroy its very foundations, that armed factions would kill each other and the national leadership. They are certainly glad that Arafat is dead and pray for the failure of Mahmoud Abbas.

Arafat assured me once that we would both see peace in our lifetime. He was prevented from seeing the day. He who caused this - whoever he is - has sinned not only against the Palestinian people, but also against peace, and therefore against Israel.

An Odd Birthday Party

Yesterday, on the eve of my 82nd birthday, I had a very unusual party. Emotions ran high, tears flowed as never before, there was a long parade. The whole thing took place in a West Bank village called Bil'in.

True, the tears were caused by gas. Emotion ran high because we were viciously attacked by the Border Police. The parade was in protest at the Separation Fence, which cuts off most of the land of the village in order to enlarge the huge Modi'in Ilit settlement.

For months now, Israeli peace activists have joined the villagers every Friday in a protest march to the site of the fence, turning Bil'in into a symbol of non-violent resistance. The site has already been leveled, but the fence itself has not yet been built in this sector. Last week's demonstration was attacked by the army with special brutality, so we decided to come back in force this week.

There were more than 200 of us - protesters from all over the country, belonging to various peace movements. Before setting off, we had already heard on the radio that the village had been invaded at daybreak, that a curfew had been imposed and that violent clashes were taking place. Since all the regular routes into the village had been blocked, we had to approach from an unexpected direction.

Leaving our buses on the edge of the settlement, we started on our way through a typical Palestinian landscape - steep hills covered with slippery rocks of all sizes, olive trees, thick dry brush and thorns. The temperature had climbed to 30 degrees in the shade, but there was no shade in sight. I didn't like walking there when I was a soldier, and now, 57 years later, I like it even less.

For two endless hours we climbed up and down, slipping now and again, helping each other. We were a motley lot - youngsters of both sexes, elderly people and everything in between. When I was almost at the end of my tether, I reached the site of the fence, a bright, long wound winding like a snake through the valley. Rachel, no spring chicken either, had the eerie experience of her legs just refusing to take orders from her brain. She was unable to move. But eventually she made it, too.

The first contingent crossed the ribbon and climbed the next hill towards the village, where they were surrounded by the Border Police in front of the mosque. I and the rear contingent were stopped at the site of the fence by soldiers and policemen, who reminded us that we were guilty of entering a "closed military area". Using threats and enticement, and noticing our pitiful state after the strenuous march over the rocks, they offered to convey us back to the Green Line in their armored vehicle, granting us the status of "detained". Except for a few who were close to fainting, we refused.

Life is full of surprises. Suddenly an army jeep drove up and offered us ice-cold water. Since we were all by now in various stages of dehydration, we accepted. (I imagined a soldier offering a girl a cup of cold water, asking "with or without gas?")

Thus fortified, we dispersed among the olive trees and started to walk towards the village. It was a very steep climb over the rocks, worse even than before. Half way up, I was overtaken by two young army officers. "Wouldn't you consider coming back with us?" they enquired politely. I declined with equal civility. And then the incredible happened: They bade me farewell and disappeared.

I climbed on, reaching the village just when I felt that I could not take one more step. Approaching the mosque, I was met by the pungent smell of tear gas. I already had half an onion in my hand - for some reason, onions, which generally cause people to shed tears, have an uncanny interaction with tear gas, making the gas almost bearable. I had one clutched in my hand throughout the day.

Our contingent was welcomed with much enthusiasm by our comrades who had already reached the mosque, as well as by the villagers. The scene resembled a battlefield - armored jeeps were racing around, the regular percussion of stun grenades and tear gas canisters was a background music, hardly noticed, and from time to time a barrage of gas drove us into the adjoining courtyards.

How to proceed? We had reached the village against all odds, we had demonstrated our solidarity, the radio had announced the events every hour. However, we decided that the job was not complete. We had come to march to the fence together with the villagers, and we wanted to prove that even the brutal occupation of the village would not prevent this. So we marched out again, back down the way we had come. Curiously enough, the site of the fence was abandoned. We marched along it for a few hundred yards and then we climbed again towards the village, slipping on the same rocks we had already cursed before.

If we thought that that was it, we were wrong. While we were waiting in front of the mosque for transportation by Palestinian vehicles, there suddenly roared up a long column of armored jeeps, which deployed around us. Soldiers sprang out, waving their guns and shooting gas in all directions. It was an unprovoked and quite unnecessary show of force which was, of course, met with a hail of stones from the village youth.

Eventually we got out of there, conveyed by Palestinian drivers over interior roads, and reached our buses. There I regretted only one thing: the day before I had bought some bottles of wine, to celebrate my birthday in the bus on the way back. Hearing the news in the morning and expecting violence, I thought this was no appropriate occasion for such a celebration. However, I was wrong. The activists, dead tired but high-spirited after having accomplished the mission, seemed quite ready to celebrate, but the wine had been left at home.

Now I am faced with the task of drinking eight bottles of French Merlot on my own.
