Re: the iPhone: when any country has the golden keys, every country has the golden keys. How hard is it to. Get that through your head. The moment the US demands golden keys, China is going to demand their own set of golden keys, followed by Saudi Arabia and any other foreign adversary. These keys are going to be used the same way the US is going to use them (spy on allies and enemies) as well as for seeking out minorities and problematic citizens.
As a foreigner, if something doesn't cross the US Senate of all bodies because of ethics or surveillance problems, that's really saying something. These are the people that brought us laws like the PATRIOT ACT and the CLOUD act, systematically expanding the reach of US law enforcement across borders. The EU, supposedly an ally, had to negotiate a quick, likely invalid or quickly overturned bandage treaty to make it legal to even just store personal data on US company servers. Is this what the US wants to become? A risk to their own allies?
Forcing weak encryption is not defence, it's offence. It's hard to believe that people like these aren't jealous of the spying network China has set up.
