Almost 75 years since the adoption of the first General Assembly resolution in 1946, which committed the UN to the goal of ridding the planet of nuclear weapons, "the world continues to live in the shadow of nuclear catastrophe", Secretary-General Antonio Guterres said in his message commemorating the day.
Relationships between States possessing nuclear weapons are characterized by "division, distrust and an absence of dialogue", he warned, noting that as they increasingly choose to pursue strategic competition over cooperation, "the dangers posed by nuclear weapons are becoming more acute".
According to the UN chief, all States have a responsibility to ensure that such deadly armaments "eliminated completely" from national arsenals.
Drawing attention to the wide range of global fragilities brought about by COVID-19 - from pandemic readiness and inequality to climate change to lawlessness in cyberspace - the top UN official called "preparedness to address the threat of nuclear weapons" one of those vulnerabilities.
"We need a strengthened, inclusive and renewed multilateralism built on trust and based on international law that can guide us to our shared goal of a world free of nuclear weapons", he said.
Pressurize nuclear powers
The UN has long upheld that the onus to lead disarmament is on the States that possess nuclear weapons.
Mr. Guterres concurred that those nations must "return to real, good-faith dialogue to restore trust and confidence, reduce nuclear risk and take tangible steps in nuclear disarmament".
He also stressed that they reaffirm the shared understanding that "a nuclear war cannot be won and must not be fought" and take steps to implement the commitments they have made.
Yet, according to Stockholm International Peace Research Institute (SIPRI), some 13,400 nuclear weapons remain today.
Moreover, the countries possessing these weapons have well-funded, long-term plans to modernize their nuclear arsenals.
And while the number of deployed nuclear weapons has significantly decreased since the height of the Cold War, SIPRI attests that not one nuclear weapon had been physically destroyed pursuant to a treaty.
Additionally, no meaningful nuclear disarmament negotiations are currently underway.
Mr. Guterres emphasized that the death, suffering and destruction caused by the atomic bombing in Hiroshima and Nagasaki "must not be repeated".
"The only guarantee against the use of these abhorrent weapons is their total elimination", spelled out the Secretary-General, adding that the UN "stands ready to work with all States to achieve this shared goal".
