In a week potentially overshadowed by Trump's threat of a nuclear war with North Korea, there are some reasons to be optimistic. The United Nations General Assembly has resumed and has held a signing ceremony for the new nuclear ban treaty.

On September 20, the treaty which was voted on in July, opened for signature. The treaty was a result of years of efforts from civil society and a conscious shift in focus from security and deterrence arguments to one's based on the humanitarian perspective. This humanitarian perspective argues that human beings will be the ones who suffer after a nuclear attack, and that no country would be able to adequately respond to a humanitarian catastrophe a nuclear attack would pose.

122 countries voted for the treaty to be passed back in July of this year, and so far 50 countries have signed the treaty. It will enter into force 90 days after 50 countries have ratified or acceded to it. See which countries have signed here.

Unsurprisingly, none of the 9 nuclear armed nations, including the UK have signed the treaty. In fact, the UK is amongst the states who staged a protest when the treaty was created and say they will never sign.
