VIENNA (AFP) – The United States and Britain on Monday for the first time attended a global conference discussing the risks posed by nuclear weapons, reversing their snubbing of previous rounds.
The two countries are permanent UN Security Council members and among the nine states con-firmed or believed to possess nuclear weapons, but shunned gatherings held in Norway last year and Mexico in 2014.
Monday’s meeting featured some 800 delegates from close to 160 countries discussing the world’s 16,300 nuclear weapons.
Other weapons holders present in Vienna were Pakistan and India, but Russia, France and China did not send official delegations, although a Chinese think-tank close to the country’s government was present, organisers said.
Other no-shows were North Korea, which has conducted three nuclear tests, and Israel, widely assumed to be the Middle East’s only atomic-armed state, although it has never acknowledged it.
The two-day meeting focused on the potential short- and long-term humanitarian consequences of a nuclear explosion, the impacts of nuclear testing and the risks of an accidental atomic blast.
It included Setsuko Thurlow, 82, a wheelchair-bound survivor from the US atomic bombing of Hiroshima, Japan in 1945, who made an impas-sioned speech warning against the “ultimate evil” of nuclear weapons.
Nuclear weapons have only been used in war twice – in Nagasaki and Hiroshima – but there were more than 2,000 test explosions between 1946 and when the practice largely halted in the 1990s.
The largest test by the United States, in Bikini Atoll in the Pacific in 1954, was 1,000 times more powerful than the Hiroshima blast.
The USSR’s “Tsar Bomba” in 1961 was bigger still.
“As long as nuclear weapons exist, the risk of their use – deliberately or inadvertently – remains real. Such a scenario, more than any other human action, has the potential of ending life on this planet as we know it,” said Sebastian Kurz, foreign minister of hosts Austria.
Ahead of the conference a group of 118 states-men and women from 46 countries issued a joint statement warning that the risks posed by nuclear weapons “are under-estimated or insufficiently understood by world leaders”.
“In a vestige of the Cold War, too many nuclear weapons in the world remain ready to launch on short notice, greatly increasing the chances of an accident,” the statement said.
