Why are you assuming that people in China, Iran, Russia etc are not having these exact same conversations, and perhaps a powerful example from the USA, along with some belief that the USA will not be able to easily get this technology, help inspire them to abstain as well?

However horrific the regimes in these countries are, the people behind the technology there are just as likely to be intelligent and moral human beings as the people in the USA and Europe working on these are.
