about as effective as the banning of chemical weapons. not that is not a great idea but the NPT is better acted on. a treaty such as this ban requires rational actors and we have one fully irrational country (NK) and a few other suspect ones that might even employ proxies to use the weapons. the real question about such a treaty is, say you could get China, Russia, and the US, to agree. How do you disarm nations that won't. You could try trade sanctions but that is likely to cause the irrational to use their weapons. I do like the idea of signatory nations not allowing such weapons on their territory but giving the current theory on their usage what does that gain?
