Here's a definition of ESPIONAGE that i found:
Assange didn't commit espionage to obtain the information. It was given to wikileaks by most likely a member of the US military. It's not espionage, nor is 'exposing classified documents' considered espionage. The fact that such classified information is leaked through this particular website is NOT proof that said website used espionage to obtain it. That's not proof that Assange is a spy, a head of a spy ring, a hacker, or assisting or being an accessory to spies.
Sounds like he does all of that
ALSO you can't technically "STEAL" information/ideas anyway, so most of your arguments regarding it being "Stolen" are irrelevant. "Unlawful reproduction" or transmission would be more appropriate, i guess. So just replace all of those terms with stolen and it should be AOK. The only way you can really "Steal" information is if you use it first, claim it was yours and/or get the benefits.
