Sure, crypto is hard, but I don't think for the last 20 years or so we have been living in a world where the five countries (and one specially-administered territory) mentioned in the article as having received the software (China, Hong Kong, Russia, Israel, South Africa, and South Korea) would have significantly more trouble than a private company in the U.S. producing secure cryptographic software based on known algorithms and protocols. The only consequence of export restrictions on crypto beyond the things that live in the classified/military world, is reducing the competitiveness of American software firms and decreasing economic output by having every piece of security software developed twice, once in the U.S. and once in say Switzerland or India or whichever country doesn't have insane export restrictions on crypto.
