Question

why does India want ban on atomic arms

Answer 1

Over 120 countries in the United Nations voted to adopt the first-ever global treaty to ban nuclear weapons, even as India and eight other nuclear-armed nations, including the US, China and Pakistan did not participate in the negotiations for the legally binding instrument to prohibit atomic weapons.

Answer 2

More than 120 nations adopted the first international treaty banning nuclear weapons on Friday at the United Nations headquarters in New York City. The initiative—led by Austria, Brazil, Mexico, South Africa, and New Zealand—was approved by 122 votes, with only the Netherlands opposed, and Singapore abstaining. The nine countries generally recognized as possessing nuclear weapons—the U.S., Russia, Britain, China, France, India, Pakistan, North Korea, and Israel—were noticeably absent from the negotiations, as were most members of NATO.
this is one of those reasons why India ban atomic arms.
