Nobel Peace Prize nominee Dr Helen Caldicott fears US President George Bush's re-election will lead to Armageddon and she isn't sure if mankind would survive another four years.
"This is the most serious election that has ever occurred in the history of the human race, without a scrag of doubt," she told smh.com.
"I don't know if we'll survive the next four years ... I don't think the Americans have, on the whole, the faintest idea - and I have to say also I don't think most Australians do either. But it's not just the threat from nuclear war. It's the threat of what's happening to the environment, the global warming which is occurring rapidly now, to ozone depletion, to species extinction, to deforestation - it's the whole thing."
Speaking from her son Will's Boston home, the Australian paediatrician, who runs the Nuclear Policy Research Institute in Washington, has just spent a frantic two-and-a-half months criss-crossing America to deliver her anti-nuclear and anti-Bush message. She discovered the country was more divided than at any time since she first stepped onto American soil in 1966.
Early on election day she was convinced Democratic challenger John Kerry would win but reality soon set in.
"This is what I've been afraid of and I actually can't believe it's happening," she said. "The voter turnout was so high, which should have supported Kerry.
"I don't think I've ever felt so personally, politically devastated in my life and that includes when [former president Ronald] Reagan won a second term of office - which was pretty devastating for me as I was so heavily involved in the anti-nuclear movement in those days.
"But this is worse, these people are much worse than the Reagan people."
