Which countries have nuclear weapons and how many?

Update : 04 Apr 2016, 12:55 AM
The Nuclear Security Summit that just ended Friday in Washington, DC wrangled over several thorny nuclear proliferation and terrorism issues, and involved over 50 countries. But the two countries on everyone’s mind were North Korea, China and Russia. North Korea, because of its recent nuclear and missile programme. China, because they have started on the world’s largest nuclear build-up in 50 years. And Russia, because they decided not to attend at all. But many other countries, including the US, have known stockpiles of nuclear weapons. Nine countries together possess more than 15,000 nuclear weapons; the US and Russia possess 93% of them. The US and Russia maintain roughly 2,000 of their nuclear weapons on high-alert status – ready to be launched within minutes of a warning. The failure of the nuclear powers to disarm has heightened the risk that other countries will acquire nuclear weapons. The only guarantee against the spread and use of nuclear weapons is to eliminate them without delay. Although the leaders of some nuclear-armed nations have expressed their vision for a nuclear-weapon-free world, they have failed to develop any detailed plans to eliminate their arsenals and are modernising them. While the exact number in each country’s arsenal is often a closely guarded secret, some information is publicly available. Here’s a breakdown of nuclear arsenals by country, based on data from leading experts in nuclear estimates.
