Trump's post in full:

Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis. [Russia and China aren’t testing right now, but they might if the US does!] That process will begin immediately. [Expected time to ready a test is ~2 years]

Because of the tremendous destructive power, I HATED to do it, but had no choice! [Not his decision, but OK.] Russia is second, [it’s first] and China is a distant third, but will be even within 5 years. [probably not that soon.]

😆 Anyone who dislikes cool Mars rocks is advised to leave the chat immediately!

Happy for someone more knowledgeable to contradict me if I'm wrong here, but this is my understanding of why we still care about this problem.

Also, there's the whole "harvest now, decrypt later" thing, which means quantum attacks on encryption could still be important even after PQC is implemented. We're basically relying on the encrypted information becoming obsolete in the window of time before there's a capable enough quantum computer

I also rolled my eyes at that headline. But NIST setting out post-quantum encryption standards is not the same as them actually being implemented. That is going to take a lot of work over, I believe, at least a decade. Given, uh, *gestures at everything* I wouldn't say the problem is solved.
