Yes also due to a huge increase in regulation. Which makes sense with the capability of some of these things, don't get me wrong. But it's no longer a fun hobby.

> Second, there are possible paths to have a winnable nuclear war, actually, the US did have one a couple of decades ago and it won.
Well yeah because at that time they were the only one who had a nuclear bomb. That situation didn't last long.
I think it's really great that it's such a taboo, otherwise these things would be used a lot, incurring all sorts of pollution, mass casualties and chances to escalate. It's a good thing that these have not been used since WWII though I do think their existence as a deterrent has brought us a bit more peace.
It won't be the only solution that can do this by the way. Many airplane WiFi services block WhatsApp and telegram calls.
I think they just look at the traffic shape. Real-time traffic requires a lot of constant similar sized traffic per second, rather than texting or images which is much more bursty.
It won't be as easy as that because you can generate a private key multiple times and notice it's the same.
However yes a very limited entropy in the private key is much harder to detect especially because on this kind of device you can't see the private key directly.
Hmm yes but it's possible to compromise private key generation to only create a very small predictable subset of keys. In fact some smartcards from Infineon suffered from this as a bug. And thus they can be brute forces. It requires some serious crypto chops to determine if this is the case. Obviously it's not like the first 60 bits being zero or something. And the private key is made to not be extracted in this kind of device making it even harder.
