Indeed. Compromising cybersecurity as a means of defense is fighting with a gripless sword. It makes no sense that planting backdoors in all of your systems is somehow supposed to help security.

For one, there has been little appreciable gain from this practice, but it's also way too easy for an adversary to subvert a backdoor planted for purposes of peeping around, and use it to do very serious damage. The more entrenched surveillance via cyberespionage becomes, the more it expands the attack surface for a foreign actor to exploit it.

Second, there is no guarantee at all that the NSA is impervious to the same sort of infiltration methods. If they become compromised themselves by a foreign hacking entity, then that's it for everyone they're "surveying".
