I can foresee a world without nuclear weapons. It will be a world with no terrorist organisations, and one where all countries operate as closely as those in Western Europe, when war is inconceivable. Considering recent history, it is worth remembering that Germany today is a very close ally of France, the UK and the USA - for those past a certain age, this is a difficult concept to grasp (it was for Margaret Thatcher for example).
However,
Barack Obama's declaration that he will convene an international summit to look at the elimination of nuclear weapons is hopefully just posturing, because the global environment to abolish nuclear weapons is far from benign.
Start with Russia, which has a government that is anything but transparent, and which could not be trusted to verifiably eliminate nuclear weapons any better than the old Soviet Union. As long as Russia remains an aggressive mini-power that seeks to exercise power outside its borders rather like the USSR did, then it would be wholly wrong to remove the nuclear deterrence. It would be a brave politician who predicts an economically beleagured Russia could not threaten its neighbours again.
Then there is China. You think it would abolish nuclear weapons? Not with Russia having them of course, nor India. China also is far from having a government that could be trusted to verify abolishing its nuclear arsenal.
North Korea's existing nuclear capability, and Iran's planned capability both do not bode well. It would also be madness to remove the nuclear deterrent from the Korean peninsula, nor to remove the ability to deter Iran. Finally, will India or Pakistan blink first? While Pakistan remains an unstable state, that risks falling to Islamism, you must wonder why India would remove its arsenal?
I need not state why Israel would never abolish its nuclear option either, given the existential threat it faces from Iran and others.
John Key and Phil Goff have parroted support for it. Sadly neither noted that nuclear weapons kept the peace in the Cold War between those countries that held them. New Zealand included of course.
As long as there remain state enemies of open transparent liberal capitalist societies, nuclear weapons should be held by the Western allies. The alternative are those who execute political opponents, censor opposition and wish to command control over the West having a monopoly on nuclear weapons. That is utterly unthinkable.
