核武器可以没有，但核能力必须保留，这与政权存立深度绑定，因此意味着“不可被推翻”。如果在美国压力下彻底拆除关键设施，放弃高浓缩铀的能力，不仅削弱技术积累，也会向内部精英发出一个信号：最高领导层在核心安全议题上可以退让。对于一个以革命合法性为基础的体制而言，这种信号的破坏性远大于技术层面的损失。
One of the most important countermeasures against credential abuse is the ability to ban users who behave badly. This sort of revocation happens all the time on real sites: for example, when a user posts spam on a website, or abuses the site’s terms of service. Yet implementing revocation with anonymous credentials seems implicitly difficult. In a non-anonymous credential system we simply identify the user and add them to a banlist. But anonymous credential users are anonymous! How do you ban a user who doesn’t have to identify themselves?
