It's not about proof. It's about the concept of disclosing information - don't use strawman arguments. Fine - let's assume he had a voice recorder.
Well, you'd then say that McMoist would have to be a complete asshole to record your private conversations and forward them to your boss. And hey! That's exactly what's happening in the world right now. Diplomats TRUSTED that the cables wouldn't get out - now this trust is tainted. You probably wouldn't want to talk to McMoist again if you knew AFTERWARD that he is recording your private convos and sending them to your boss, would you?
Now the diplomatic relations of some countries with the US are ALSO strained because of the whole Wikileaks incident.
People should not be afraid of their governments.
How did the cables make people less afraid of governments? They only served DIPLOMATIC purposes.
These cables DO server an important purpose, for showing how our hired officials AND country ambassadors behave and conduct themselves.
Oh really? If you didn't know how they behaved before the cables were released than you must have been living under a rock since, well, since you were born. Everybody knows that diplomats aren't thinking what they are saying BUT international relations rely on people acting what is being said, not what is being thought. By disclosing the cables you are disclosing what people are THINKING and by the sole fact of releasing this info it all of the sudden BECOMES relevant internationally.
I'm still waiting to hear who's fates are going to be effected by this exactly... i should really get a magazine.
Let's say you're a US ambassador in an unstable country. For the sake of keeping relations healthy you obviously were nice to the locals even though they were fanatical morons - which you informed the US government about because decisions have to be made based on how things really are. Now your notes are disclosed. Do you think this guy will be safe in that country? How many American flags have been burnt already because of Wikileaks? It's stirring up nothing but hate for no particular reason other than some lofty ideals that could only be upheld in a perfect world.
Past Wikileaks, uhm, leaks were completely different to this one - they were about things the government didn't want people to know but which were cases where these cover-ups actually affected individual people and families and involved the possible stretching or breaking the laws by the government. No laws were broken by the US government in this case - other than saying what you think.
