It is again the american tendency to overcomplicate things and to think everyone shares their viewponts. Just like Al-kaeida didn’t need supreme technology to conduct their 11/9 attacks, only some knives and determination, both of which existed 3000 years ago, no terrorists need the ultrasophisticated modern encryption schemes. All it takes is a bit of innovation, of which they have plenty. It is very typical for the americans to try and block this encryption threat – you can easily gain political support and show you are doing something, no matter how unnecessary and/or ineffective it is. Much easier then dealing with the real problems. That’s politics.
