“The next process is going to be signing on to the treaty. It’ll open for signature at the U.N. in New York on the 20th of September. And after that, they’ll have to go through a national ratification process in order for it to enter into force. But that should all happen within the next year or two, and then it will be international law that is binding on all of the countries that have adhered to it, which means, in some cases, they’re going to have to change their practices and policies that may enable or facilitate the use or the possession of nuclear weapons.
“There could be economic divestment, for example, from nuclear weapon-producing companies. There could be changes of national law that currently permit transit of nuclear weapons through territorial waters. There could be different shifts in policies and practices around military training exercises that currently involve the preparation to use nuclear weapons. And it will also be an iterative process of building up the stigmatization and the norm against nuclear weapons through the public policy, through parliaments and through national discourse.”
