Intelligence is very important in any type of warfare. In my opinion it is this kind of leaking that makes Snowden a traitor. It's time for Mr. Snowden to mysteriously slip down a flight of stairs and die. Of course I'm sure Putin is guarding his little show monkey closely.
You're right. Spying on your allies (say, r example, Australia) is definitely how you enact better warfare. Planning in conquering us, are you?
I have an idea. Stop looking at everything in terms of warfare and wake the hell up...
There are no such thing as "allies"; there are only temporary interests. At the moment, Australia's interests mostly align with our own; that can change at any moment.
Everything does not need to be seen in terms of warfare, but people who insist on others sleeping is setting everyone up for serious consequences.
