The NSA&#x2F;US Intelligence can compromise small groups through other means, by either tailoring some sort of exploit or by going through the ol&#x27; hitting them with a wrench till they spill their secretes routine.<p>I&#x27;m not saying that currently in theory you cannot deploy or implement NSA foolproof crypto, I&#x27;m saying that in practice it will never work because the NSA mandate is to be able to break it and they&#x27;ll will do everything in their power to maintain those capabilities.<p>And unless some one thinks that abolishing the NSA is a realistic possibility then you better pick your fights, because while the NSA all other US defense organizations are more or less superior to all others because the USA sees dominance and force projection to be vital to their national security China, Russia, and probably major EU powers aren&#x27;t that far behind.
