How is that difficult to comprehend? Crappy leaders have been oppressing, suppressing, and duping their people for centuries. Look at Kim Ding Dong of N. Korea and "Fiddle Faddle" Castro of Cuba. Then there's the warlords in Africa, etc. Hell, even the USA has one sitting in the Oval Office right now!
You better hope Ahmadinejad's goons aren't tracking your Internet communications. Given the suppression and oppression going on there, we might not hear from you for a very long time!
