We’re freaked about Iran, but what other countries already have nukes?

There has been a lot of press around the Iran deal and whether it’ll actually prevent Iran from manufacturing a nuclear weapon. But what other countries — besides the U.S. and Russia — have nukes?

There are two categories in which these countries fall in, those who have signed the Treaty on the Non-Proliferation of Nuclear Weapons – also known as Non-Proliferation Treaty or NPT – and those who have not. The goal of the treaty is to prevent the spread of nuclear weapons, disarm existing ones and promote cooperation in the peaceful use of nuclear energy.

This TestTube News video identifies the nations that have nuclear weapons – whether they admit it or not – and those who have signed the NPT:

NOW: 7 times the U.S. military lost nukes (and 4 times they were never found)
