Why talk of a Japanese nuclear option is resurfacing – and why it alarms critics
Conservatives are calling for a rethink of nuclear taboos, while critics warn of risks to the global non-proliferation regime
The conservative daily argued that growing threats from Japan’s neighbours meant no option for protecting the public should be beyond discussion, a stance that has drawn praise from some on the right and alarm from critics who warned that even signalling such intent could destabilise the global non-proliferation system.
The editorial, published on Monday, was accompanied by a graphic comparing regional nuclear forces, stating that Russia has an estimated 5,580 nuclear warheads, North Korea around 50 and China about 500, with the latter figure projected to rise to more than 1,000 by 2030.
It appeared 10 days after the senior national security official in the Prime Minister’s Office said – in an off-the-record remark reported by Japanese media during a background briefing – that he personally believed Japan should possess nuclear weapons.
The remarks prompted a fierce reaction at home and abroad, including from Beijing, where Guo Jiakun, a spokesperson for China’s foreign ministry, told reporters the situation was a “serious issue that exposes the dangerous attempts by some in Japan to breach international law and possess nuclear weapons”.
“China and the rest of the international community must stay on high alert and express grave concern,” he added.
