Marilyn Waring on the Australian hero of nuclear-free New Zealand

The former National MP whose decision to support anti-nuclear legislation led to the 1984 snap election writes on the transformative influence of the passionate Australian physician Helen Caldicott, who speaks in Auckland this week

If you were growing up in New Zealand and Australia post World War II, there’s a chance you knew about the United States using the Marshall Islands as a nuclear testing site from 1947 until 1962. In an agreement signed with the United Nations, the US government held the Marshall Islands as a “trust territory” and detonated nuclear devices in this pristine area of the Pacific Ocean – leading, in some instances, to huge levels of radiation fall-out, health effects, and the permanent displacement of many island people. In all, the US government conducted 105 underwater and atmospheric tests. You would have also known that the British conducted seven atmospheric tests between 1956 and 1963 on traditional Aboriginal land, in Maralinga, Australia.

It may be that you read Neville Shute’s 1957 novel On the Beach, in which people in Melbourne, Australia wait for deadly radiation to spread from a Northern Hemisphere nuclear war. This book made a memorable impact on Helen when she read it as a teenager.

Both Helen and I saw Peter Watkin’s The War Game, a BBC documentary drama about nuclear war and the consequences in an English city. In New Zealand the film was restricted for children unless accompanied by an adult, so I had to get my father to take me. The War Game won the Oscar for the best documentary in 1965.

France began its series of over 175 nuclear tests at Mururoa, in the South Pacific, in 1966. At least 140 of these tests were above ground. In 1973, the New Zealand and Australian governments took France to the World Court for continued atmospheric testing, and forced the last tests underground. The testing finally came to an end in 1976.

In New Zealand the US Navy made regular visits between 1976 and 1983 with nuclear-powered and, most likely, nuclear-armed, ships. These visits produced spectacular protest fleets in the Auckland and Wellington harbours, when hundreds of New Zealanders — in yachts of all sizes, in motor boats and canoes, even on surf boards — surrounded the vessels and tried to bring them to a complete stop. By 1978, a campaign began in New Zealand to declare borough and city council areas nuclear-free and, by the early 1980s, this symbolic movement had quickly gained momentum, covering more than two-thirds of the New Zealand population.

Helen Caldicott and I had not met up to this point, but these were shared parts of our history and consciousness when Helen visited New Zealand in 1983.

Helen Caldicott graduated with a medical degree from University of Adelaide Medical School in 1961. She moved to the United States, becoming an Instructor in paediatrics at Harvard Medical School and was on the staff of the Children’s Hospital Medical Centre in Boston, Massachusetts. In the late 1970s, Helen became the President of Physicians for Social Responsibility. This group was founded when Helen was finishing medical school, quickly making its mark by documenting the presence of Strontium-90, a highly radioactive waste product of atmospheric nuclear testing, in children’s teeth. The landmark finding eventually led to the Limited Nuclear Test Ban treaty, which ended atmospheric nuclear testing.

But it was the Three Mile Island accident that changed Helen’s life. An equipment failure resulted in a loss of cooling water to the core of a reactor at the Three Mile Island Nuclear Generating Station in Pennsylvania, causing a partial meltdown. Operator failure meant that 700,000 gallons of radioactive cooling water ended up in the basement of the reactor building. It was the most serious nuclear accident to that date in the US Helen published Nuclear Madness the same year. In it she wrote: “As a physician, I contend that nuclear technology threatens life on our planet with extinction. If present trends continue, the air we breathe, the food we eat, and the water we drink will soon be contaminated with enough radioactive pollutants to pose a potential health hazard far greater than any plague humanity has ever experienced.” In 1980, Helen resigned from her paid work positions to work full time on the prevention of nuclear war.

In 1982, Canadian director Terre Nash filmed a lecture given by Helen Caldicott to a New York state student audience. Nash’s consequent National Film Board of Canada documentary If You Love this Planet was released during the term of US President Ronald Reagan, at the height of Cold War nuclear tensions between the United States and the Soviet Union. The US Department of Justice moved quickly to designate the film “foreign propaganda,” bringing a great deal of attention to the film. It went on to win the 1982 Academy Award for Documentary Short Subject. That same year, Helen addressed about 750,000 people in Central Park, New York in the biggest anti-nuke rally in the United States to that date.

In 1983, I was serving as a member of the New Zealand parliament, having been elected eight years earlier at the age of 23. Our parliament established a Disarmament and Arms Control Select Committee to conduct hearings on the possibility of making New Zealand a nuclear-free zone. During this critically important time, Helen was invited to New Zealand on a lecture tour. The documentary If You Love This Planet was shown at her speaking engagements.

I did not get to meet her, nor hear any of her lectures in person, as I was working in parliament every night. But I did follow the media coverage.

Helen told the Listener about having observed five-star generals in US congressional and senate committees complaining that the Russian missiles were bigger than the American ones. “The Russian missiles are very big [and] inaccurate and clumsy. America has very small, very accurate missiles, which are better at killing people and destroying targets,” she explained. A frequent message in her talks to New Zealand audiences was the redundant overkill capacity of both superpowers. Caldicott noted to her audiences that “The US has 30,000 bombs and Russia 20,000.”

I had sat in a New Zealand parliamentary committee hearing some months earlier, when a government colleague, brandishing a centrefold of a Russian submarine, excitedly called for us to “Look at how big it is.” I had thought that no one would believe me if I had repeated such an inane banality – when an adult male was more impressed by the size of the submarine than its capacity to destroy life on this planet.

Helen’s public addresses were grounded in the potential impact of nuclear weapons. “Imagine a 20-megaton bomb targeted on Auckland,” she told audiences in New Zealand. “The explosion, five times the collective energy of all the bombs dropped in the Second World War, digs a hole three-quarters of a mile wide by 800 feet deep and turns people, buildings and dirt into radioactive dust. Everyone up to six miles will be vaporised, and up to 20 miles they will be dead or lethally injured. People will be instantly blinded looking at the blast within 40 miles. Many will be asphyxiated in the fire storm.”

Helen did not hold back, explaining that nuclear war means “blindness, burning, starvation, disease, lacerations, haemorrhaging, millions of corpses and an epidemic of disease”. Helen’s dramatic and blunt style reduced many in her audiences to tears. She always ended her talks with a call to action – especially to parents – as she strongly believes that nuclear disarmament is “the ultimate medical and parenting issue of our time.”

To those who would claim New Zealand was not a target she had a short reply: “Trident submarines in ports are targeted. They are a first strike target. It is much easier to destroy subs when they are in dock than it is when they are submerged in the ocean.”

In 2015, I asked Helen how she managed to deliver such bad news and yet keep her audiences with her. “Being a doctor helps because you have to learn to negotiate with a patient and with language they can understand,” she explained. “You have to convert the medical diagnosis and treatment to lay language. I also have to keep them awake sometimes by letting them laugh because it relieves their tension and because the stuff I say is pretty awful.” Helen told me that she practises “global preventative medicine”.

Helen’s tour through New Zealand in 1983 had a huge, and lasting, impact. At one stop, Helen addressed over 2,000 people at a public event in Auckland. The librarian with whom I corresponded looking for old newspaper reports of Helen’s visit, wrote to me: “Her chillingly detailed description of the effects of a nuclear device detonated over the hall in which we were sitting remains rooted in my psyche to this day! …The other message I most recall is the dichotomy she evoked between the destructive drive of ‘old men’ rulers, the instigators of war, versus the procreative energy of mothers most impelled to oppose them — which, however reductive, retains the compelling logic of a truism!”

Helen’s approach was transformative in New Zealand. Helen’s speaking events packed auditoriums, and overflows of audiences had to be accommodated using loud speaker systems. People responded strongly to this woman, whose life work involved caring for children, speaking about medical effects of fallout, and speaking without the use of the clichéd military and defence ideological rhetoric that treated people as if they were simpletons who couldn’t understand. Her speeches inspired people to act. After Helen spoke, the volume of mail delivered to my parliamentary office increased—particularly from women.

On May 24, 1983, 20,000 women wearing white flowers and armbands and holding banners with peace signs marched quietly up a main street in Auckland to hold a huge rally and call for New Zealand to be nuke-free. It was one of the largest women’s demonstrations in New Zealand’s history. In her book, Peace, Power and Politics – How New Zealand Became Nuclear Free, Maire Leadbetter writes: “I am one of many activists who think of Helen Caldicott’s visit as the point when the peace movement began to grow exponentially … Helen had a magical ability to motivate previously passive citizens to become activists.”

Shortly after Helen’s visit to New Zealand, in 1984, I advised that I intended to vote for the opposition-sponsored nuclear-free New Zealand legislation. This prompted conservative Prime Minister Rob Muldoon to call a snap election. Muldoon told media that my “feminist anti-nuclear stance” threatened his ability to govern.

The new Labour Government of 1984 passed the New Zealand Nuclear Free Zone, Disarmament and Arms Control Act in 1987, the world’s first national nuclear-free legislation. Dr Helen Caldicott’s influence had culminated in the passage of the cornerstone of New Zealand’s foreign policy.

This essay is one of 28 stories by notable women about remarkable women peacemakers, When We Are Bold: Women Who Turn Our Upsidedown World Right, to mark the 10th anniversary of the Nobel Women’s Initiative. Dr Caldicott speaks at AUT on Tuesday November 15.
