Speculation has risen about whether Ms. Takaichi, who supports nuclear dissuasion, may allow nuclear weapons to be brought into the country, going against the third non-nuclear principle. “The theory of nuclear deterrence is extremely dangerous and fragile. Nuclear weapons are ‘not a necessary evil but an absolute evil,’ and can never coexist with humanity,” Mr. Suzuki said. “To all leaders of the nuclear states and nations relying on nuclear deterrence, you must face the reality that the more you rely on nuclear deterrence, the more you increase the risk of a nuclear war.” The Prime Minister, who attended Sunday’s ceremony, reiterated her policy of taking “a realistic and pragmatic approach” toward achieving a world without nuclear weapons.
