There is already a AWS GovCloud (US) Region [1], which is segregated from the conventional/general regions. This region is specific to US government agencies with improved security. Maybe the CIA would like something special for US intelligence agencies (i.e. an AWS GovCloud (classified/top secret) Region)? There is obvious advantages to the cloud when it comes to government procurement/life cycle management headaches. There is also an Introducing AWS GovCloud on YouTube [2], it's worth a watch if you are interested.
