Any thoughts?

Yeah, thank you, Anna.

I'll try to be really quick here, but I do think it's important to set the stage with sort of a taxonomy of the categories of nuclear weapons-related treaties that we'll be talking about.

The first category I would say is nonproliferation treaties and obligations.

These obligations are focused on preventing or slowing the horizontal spread of nuclear weapons.

The cornerstone of this area of law, nonproliferation, is of course the Nuclear Nonproliferation Treaty which came into force.

being in 1970, in addition to which there are safeguards treaties, export control organizations, nuclear weapon-free zones, etc., etc.

Dan, what are your thoughts about what we should be thinking about in the arms control space?
