How long would it take the NSA..

..to break AES-128 encryption? With regard to the wikileaks insurance file.

They don't need to brute force the encryption at all.
It only takes 72 hours of sleep deprivation for the human mind to crack.
They send in a Company black ops team and pluck his little terrorist  faggot ass out of the .nl (or where ever) and feed him caffeine for a long weekend, he'll spill the password.
I only wish I could help.
