History goes round and round and people hungering for freedom or food or power keep on killing and killing and killing.

There was killing and killing, and then there was Hiroshima. And if that wasn't enough, there was Nagasaki, and then there was the Cuban Missile Crisis in October, 1962.

If good sense and courage had not stayed the hands of John F. Kennedy and Nikita Kruschev and this one sailor in a Russian submarine out at sea near Cuba, chances are you and I and everyone we know would not be alive today.

Following the news on television around the world now, I see the danger, and my first instinct is to strike now! strike fast! - before ... But then I am glad I do not have to decide. I do not have my finger on that red button. I do not have to kill anyone.

And I am so grateful to those in our recent past who did not strike:

The man who saved the world: The Soviet submariner who single-handedly averted WWIII at height of the Cuban Missile Crisis.

He was the man who saved the world by single-handedly averting World War Three five decades ago, yet he died humiliated, outcast and an unknown. Only now has his story has come to light.

A documentary shown tonight told how for 13 days during the Cuban Missile Crisis in October 1962, the world held its breath as the U.S.S.R. and the U.S. stood on the brink of nuclear war.

At the height of the Cold War, when paranoia on both sides meant the slightest provocation could spark nuclear war, four submarines secretly set sail from Russia to communist Cuba.

Averted war: Vasili Arkhipoy (pictured left, and right aboard a submarine), saved the world by single-handedly averting World War Three with one decision 50 years ago, yet he died humiliated, outcast and an unknown.

Only a handful of the submariners on board knew that their ships carried nuclear weapons, each with the strength of the bombs dropped on Nagasaki and Hiroshima in 1945.

Vasili Arkhipov, aboard the sub B59, was one of them. As his craft neared Cuba, U.S. helicopters, aeroplanes and battleships were scouring the ocean for Russian subs.

'At that period of time it was called "special weapon", not "nuclear torpedo",' said Viktor Mikhailov, junior navigator on Sub B-59. 'At that time we couldn't even imagine a nuclear torpedo.'

In a game of high stakes cat and mouse it wasn't long before the Russians were spotted. Arkhipov's sub was forced to make an emergency dive.

For 13 days during the Cuban Missile Crisis in October 1962, the world held its breath as the USSR and the U.S. stood on the brink of nuclear war.

Tense: As the submariners tried to stay hidden from their US hunters, conditions in the sub deteriorated. For a week they stayed underwater, in sweltering 60C heat, rationed to just one glass of water a day.

'Basically what we were trying to do was apply passive torture. Frankly I don't think we felt any sympathy for them at all. They were the enemy'
Gary Slaughter, USS Cony signalman.

Above them, the U.S. navy were 'hunting by exhaustion' - trying to force the Soviet sub to come to the surface to recharge its batteries.

They had no idea that on board the submarines were weapons capable of destroying the entire American fleet.

Gary Slaughter, a signalman on board the USS Cony battleship, said: 'We knew they were probably having trouble breathing. It was hot as hell in there, they were miserable.

Mr President: John F. Kennedy was in office in the U.S. between 1961 and 1963, at the height of the crisis

Tense: The documentary recreated the dramatic moment when Soviet sailors decided not to fire the weapon.

'They were cramped together and they had been under great stress for a long time. Basically what we were trying to do was apply passive torture.

'They said that the person who prevented a nuclear war was the Russian submariner Vasili Arkhipov. I was proud and I am proud of my husband always'
Olga Arkipov, widow of Vasili Arkhipov

'Frankly I don't think we felt any sympathy for them at all. They were the enemy.'
The Americans decided to ratchet up the pressure, and dropped warning grenades into the sea. Inside the sub, the Soviet submariners thought they were under attack.

Valentin Savitsky, the captain of B59, was convinced the nuclear war had already started.

He demanded that the submariners launch their torpedo to save some of Russia's pride.

The programme on Channel 5 revealed how in any normal circumstances Savitsky's orders would have been followed, and World War Three would have been unleashed.

'Close friend': Ryurik Ketov, commander of Sub B-4, said Arkhipov was 'cool-headed' and 'in control'

Memories: Viktor Mikhailov, junior navigator on Sub B-59, said they had a 'special weapon' on board, which was not even referred to as a 'nuclear weapon'

Ryurik Ketov, commander of another sub, Sub B-4, said: 'Vasili Arkhipov was a submariner and a close friend of mine. He was a family friend. He stood out for being cool-headed. He was in control.'

'One of the Russian admirals told the submariners: "It would have been better if you'd gone down with your ship". Extraordinary'
Thomas Blanton, historian

Savitsky hadn't counted on Arkhipov. As commander of the fleet, Arkhipov had the last veto. And although his men were against him, he insisted that they must not fire - and instead surrender.

It was a humiliating move - but one that saved the world. The Soviet submariners were forced to return to their native Russia, where they were given the opposite of a hero's welcome.

Historian Thomas Blanton told the Sun: 'What heroism, what duty, they fulfilled to go halfway across the world and come back, and survive.

Proud: Arkopov's widow Olga said: 'I was proud and I am proud of my husband, always'

'But in fact, one of the Russian admirals told the submariners; "It would have been better if you'd gone down with your ship." Extraordinary.'

Four decades passed before the story of what really happened on the B59 sub was discovered. It was after Arkipov had died in 1998 from radiation poisoning.

But to his widow Olga, he was always a hero. She said: 'He knew that it was madness to fire the nuclear torpedo. In Cuba, in honour of the 40th anniversary of the crisis, people gathered.

'They said that the person who prevented a nuclear war was the Russian submariner Vasili Arkhipov. I was proud and I am proud of my husband always.'
