National Security Agency director Keith Alexander wants to keep his cushy, lazy ass job.
That is it in a nutshell.
However, somebody just tied Clapper together with Snowden in a koinkydink ~ they both worked for the same company!
Regarding any of their public statements these guys are not authorized to declassify anything, and just about everything about NSA is classified. That means if they say anything of substance they are either in violation of the classification rules or they are lying.
Since we have no independent way of knowing we have to assume they lie!
