US Ambassador to the UN Nikki Haley has said that worldwide nuclear ban is simply not realistic, 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.<br/><br/>More than 120 others endorsed a plan for a legally binding nuclear ban. But Haley said national security required nuclear arms because of bad actors who could not be trusted. 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.<br/><br/>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. A UN conference to negotiate a legally binding treaty to ban nuclear weapons opens in New York yesterday.
