This is pretty overwrought. There have been numerous times over the last 15-or-so years where people have quietly had the ability to spoof arbitrary certificates due to PKCS1v15 signature verification bugs – there was just this year an NDSS paper published on a whole new raft of them, and it'll be at Black Hat in August as well.

A fundamental class break that takes down RSA would be a big deal, but not a national emergency; the world is already moving somewhat rapidly towards elliptic curve systems anyways.

Spoofing certs is not comparable to breaking RSA. Also, I think for this thought experiment, you should also consider breaking elliptic curve crypto. Neither has been proven hard.

Spoofing certificates was the example given in the parent comment. We use elliptic curves specifically because they are harder, in a specific way (resistance to index calculus) than simple multiplicative group cryptography.

My point is just that nobody is going to kill you for this ability.
