OK, the UK is also evil...

"There are currently 189 states party to the treaty, five of which have nuclear weapons: the United States, the United Kingdom, France, Russia, and the People's Republic of China.

Only four nations are not signatories: India, Pakistan, Israel, and North Korea. India and Pakistan both possess and have openly tested nuclear bombs. Israel has had a policy of opacity regarding its own nuclear weapons program. North Korea ratified the treaty, violated it, and later withdrew."

So, when Iran and France get into it, the UK can throw it's bombs into the mix.
