At the launch of the 10th annual Nuclear Non-Proliferation Treaty (NPT) at the UN, Blinken pointed to North Korea’s “illegal nuclear program” and “continued provocations”, Iran’s “nuclear escalation path” and Russian aggression in Ukraine. which included seizing control of Europe’s largest nuclear power plant. “We are deeply concerned that Russia has seized nuclear facilities in Ukraine, particularly Zaporizhzhia, one of the largest nuclear facilities in Europe,” Blinken said. “There are credible reports, including in the media today, that Russia is using this plant as the equivalent of a human shield, but a nuclear shield in the sense that it is shooting at Ukrainians from around the plant, and of course the Ukrainians cannot and will not detonate lest a terrible nuclear plant accident,” Blinken added, saying it was “the height of irresponsibility.” File photo of the Zaporizhzhia nuclear power plant in southeastern Ukraine on July 9, 2019.

Grossi, the head of the international watchdog, described the war in Ukraine as “so serious that the specter of a possible nuclear confrontation or accident has reared its terrifying head again.” Grossi warned more specifically about Ukraine’s Zaporizhia nuclear power plant, saying “the situation is becoming more dangerous every day.” “It is urgent,” he said last week, as the agency has not been able to visit the site since before the conflict began five months ago. On Monday, Grossi was clear about the risks: “While this war rages, inaction is unconscionable.” “If an accident happens at the Zaporizhzhia nuclear power plant, we will not have a natural disaster to blame – we will only have ourselves to answer to,” Grossi said, adding: “We need everyone’s support.” Blinken told CBS News at a press conference that “Ukraine had the confidence to give up the (nuclear) weapons it inherited when the Soviet Union collapsed because of the commitments Russia made to respect and protect its sovereignty, its independence, its structural integrity. ” US Secretary of State Anthony Blinken speaks to the media after attending the 10th annual review of the Treaty on the Non-Proliferation of Nuclear Weapons at UN headquarters on August 1, 2022 in New York.

Blinken said. He was referring to the 1994 Budapest Memorandum, an agreement in which the United States, Russia and Britain pledged “to respect the independence and sovereignty and existing borders of Ukraine” after the collapse of the Soviet Union and “to refrain from the threat or use of force” against it — assurances that convinced Ukraine to give up “what amounted to the world’s third-largest nuclear arsenal, consisting of some 1,900 strategic nuclear warheads,” according to a Brookings analysis. The Treaty on the Non-Proliferation of Nuclear Weapons, established in 1968 to prevent the spread of weapons technology, sought to keep the number of nuclear states to a minimum – but keeping the nuclear genie in the bottle was an uphill battle. The nuclear weapon states at the time were Britain, China, France and Russia (the Soviet Union at the time), and the number of nuclear weapons they possess has declined since the height of the Cold War. But in the years since, India, Pakistan and North Korea have developed nuclear weapons, and Israel is believed to have a nuclear arsenal, although it has neither confirmed nor denied the existence of a program. Iran has been moving forward with its nuclear program since the US withdrew from the 2015 nuclear deal, but has yet to build a weapon. Iran’s nuclear chief said this week that Iran has the ability to build a nuclear weapon but has no plan to do so. The UN conference will continue throughout August and the nuclear activities of North Korea and Iran are sure to be discussed daily. North Korea “continues to expand its illegal nuclear program and continues its ongoing provocations against the region,” Blinken said. “As we gather today, Pyongyang is preparing to conduct its seventh nuclear test.” The secretary-general’s assessment of nuclear threats was chilling: “Proliferation risks are increasing and safeguards to prevent escalation are weakening.” Guterres heads to Hiroshima at the end of the week, marking the anniversary of the US nuclear bombing in World War II – an event not lost on the event’s speakers. Japanese Prime Minister Fumio Kishida said Russia’s indirect warning that it could use nuclear weapons in the Ukraine war has added “to global concern that another catastrophe from the use of nuclear weapons is a real possibility.” Blinken also indicated that he was responding to threats China has made about House Speaker Nancy Pelosi visiting Taiwan, a self-governing island that China is determined to reunify with the mainland. Blinken said: “The speaker will make her own decisions about whether or not to visit Taiwan. Congress is an independent co-equal branch of government – the decision is entirely up to the speaker.” “If the speaker decides to visit and China tries to create some kind of crisis or otherwise escalate tensions, that would be entirely on Beijing,” Blinken said. “We are looking for them, should he decide to visit, to act responsibly and not engage in any escalation in the future.” On Monday, China’s UN ambassador Zhang Jun said China would defend its security and sovereignty if Pelosi visits Taiwan. He described the possible visit as “challenging and serious”. More Pamela Falk Pamela Falk is a CBS News correspondent covering the United Nations and an international attorney.
