A worldwide nuclear ban is simply not “realistic”, the US ambassador to the UN has said, as nearly 40 countries stayed away from talks on the subject.

The US, Britain and France were among the countries that skipped a UN meeting to discuss a new treaty, reports the BBC.

More than 120 others endorsed a plan for a legally binding nuclear ban.

But US envoy Nikki Haley said national security required nuclear arms because of “bad actors” who could not be trusted.

“There is nothing I want more for my family than a world with no nuclear weapons. But we have to be realistic,” she said journalists.

“Is there anyone that believes that North Korea would agree to a ban on nuclear weapons?”

North Korea has recently been testing nuclear and missile technology, despite warnings from the international community - including China.

The UN conference to negotiate a legally binding nuclear ban treaty was announced in October.

Britain, France, Israel, Russia and the United States voted “no” to the nuclear ban treaty back then, while China, India, and Pakistan abstained.

Japan - the only country to have suffered atomic attacks, in 1945 - also voted against the talks.

Nobushige Takamizawa, Japan’s disarmament ambassador, said working on a treaty “without the involvement of nuclear weapon states [would] only deepen the schism and division” in the international community.

On Monday, Haley said: “In this day and time we can’t honestly say that we can protect our people by allowing the bad actors to have them and those of us that are good trying to keep peace and safety, not to have them.”
