The problem with having the NSA break encryption in this manner is that it's not like they've discovered a 0day and are hacking into our enemies; instead, they've corrupted the encryption, exposing what were formerly considered secure comm methods. I'm pretty sure that these corrupted comm methods aren't only available to the NSA. This gives enemies of the US an idea of how to circumvent our encryption, thus exposing everyone who uses these comm methods to attack, whether they're US allies or enemies.
