Oh, i believe that the soldier(s) who released the documents have breached their contract.
I would also suggest that for Assange to be tried for espionage, it would have to be proven that he instigated the theft of the docs. If somebody came to him and handed over the docs, then at worst it is receiving stolen goods, not espionage. However, IMO, it fits into the whistle blowing category..
As for a national security issue, I disagree. I have yet to read anything (although that could change) that has been a national security issue....
1. wouldn't you agree that we have a national security interest in having diplomats from other countries speak candidly with us?
2. wouldn't you also agree that the release of these materials would make a reasonable person from another country skeptical about communicating openly with us?
3. we don't know what information was released that will endanger others because we haven't seen the damage assessment.
4. Do you think any good comes from Putin knowing that we said that Russia is a being run like a mafia state now? does that in any way assist our relations with Russia? Or does it endanger our relationship with them and thereby is a national security issue.
