The Guardian has recently published a report on how the NSA and the UK's GCHQ have been routinely cracking cryptography used on the Internet. Seriously, this is no surprise. Lots and lots of sites routinely use "RC4" encryption, whose vulnerablility has been well known for over a decade.
I also hadn't realized the extent to which American citizens in general are considered "the enemy" by the NSA. Their duplicitous role in Internet standards is breathtaking. It may be the grandest example of social engineering. Ever.
