The NSA had nothing to do with designing Kyber.

He didnt say it did, he said "The NSA likely has orders more experience with the area of cryptography Kyber comes from than everyone who worked on Kyber"

He himself (co-)submitted a lattice KEM to the NIST competition.

Yes, and strongly argued against lattice schemes generally. DJB submitted a lattice scheme under the theory that if the advocates of lattice schemes were able to win the argument about the performance properties then there should be a choice of an extremely conservatively designed one.

DJB himself has consistently advocated for Classic McEliece in any application which can accept its performance characteristics (which are excellent except for the ginormous public keys), and spent many bytes trying to convince people that the set of applications that can is wider than they suspect.

What does this even mean? By the exact same logic you could impeach literally any algorithm.

It means that your argument is “the NSA couldn’t have subverted ML-KEM, it was written by Europeans”.

You assiduously pretend that this scenario isn’t possible: * The NSA reviewed the PQ submissions and realized that there’s one they already know how to break at scale: ML-KEM, because their army of math PhDs spent a couple decades understanding it better than the rest of the world * The NSA decides they want ML-KEM deployed everywhere so that the world is full of transparent-to-NOBUS cryptography * The NSA spends the entire PQ contest placing their thumbs on the scale of the process, violating their 2014 post-Snowden promises of increased transparency, to make their NOBUS dreams happen

The actions of NSA and NIST personnel make the most sense with the assumption that they desperately want to standardize ML-KEM and ML-KEM alone because _they already know how to break it_. What doesn’t make any sense is why the private sector is cheerfully going along with it —- even Charlie stopped letting Lucy hold the football at some point.
