So yeah - if we actually had a real President who cared about things like this, we wouldn't be talking about leaks like this weeks after the initial event. Instead, he would have been found and dealt with - one way or another. You deal with treason directly and swiftly. If not, then you have no security at all. Ever.
Problem, we have had treason going on at the highest leves for a long time in the US. And there has not been any sort of dealing with it swiftly...or at all.
Not seeing that Snowdon revelations will compromise anyone.
However the information does compromise the US leadership.
