Laws against encryption will never be international. In the US it happened before [1], so there is indeed precedent. But such laws prevent a country from being competitive in the international marketplace, therefore many countries will not agree to it, just as they aren't agreeing with IP laws. And yes, I also believe that this trend on having national firewalls for censoring content will also not last for long, for the same reason.

What I love about technology is that it cannot be stopped with lawmaking.
