OK, once again, I am the hardline minority on this brand of issue.
True transparency, if that is the aim of wikileaks, would be crippling to economies and governments everywhere - as it would be in your own household (imagine if you held a policy of true transparency with your spouse, your kids... or worse, if true transparency was forced upon you after the fact). But the stakes are much higher. If our economies were truly crippled, most of us would not have jobs, would not have social services, would not have legal recourse and would live in utter chaos - THERE WOULD BE NO GOVERNING IN AN ENVIRONMENT INIMICAL TO THE ACT OF GOVERNING.
Hate it all you want, but you benefit greatly from the system as it exists. Not to say it should not be scrutinized - I am just saying that the effective line of scrutiny is more elusive than many care to admit. There need to be checks and balances, and, as Vovin pointed out, the various news media used to fulfill this role; I am not entirely convinced that they do no longer, but i
am convinced that an unmonitored unsourced entity like wikileaks will certainly not.
To govern is to accept responsibility for protecting your people. And to think that's always pretty is, frankly, naive. The world is a dirty place, and i personally don't begrudge it that; it is the natural and necessary course of human advancement (wow, I feel the heat of the flaming from here

). It's easy from a throne of relative luxury to sing the praises of absolute transparency and accountability; but look under you, the throne that elevates you above the dangerous flotsam and jetsam below was built on a foundation of diplomatic subterfuge. Necessary diplomatic subterfuge, if you value your present life.
We all lie. To save face, for the better good, to evade pointless conflict and to win allies who help keep us safe and protect our families - in the boardroom, the ballroom and the bedroom alike. Some lies conceal good; Some lies veil certain evil; some veil acts perceived as evil out of context - and to expect us to understand the global context of all governement actions and contexts is globally unrealistic and naive.
That is why we vote. To place our trust in someone to perpetrate perceived acts of "evil" in a context of a "greater" good. It is such a very fine line, but whether you like it or not, it is a line that will always exist in a stable and effective and, ironically, equal community. So I seem to stand alone in the recognition that some things need to happen behind closed doors. Honesty is the fool's policy when absolute and bare. The only thing I demand of a politician is that their acts, overt and covert, open and secret, plain and unscrutinized, be true and honest to the principles they sold to the people who voted for them. And even this, in the scale of things, is probably naive...
Trust is not an expectation of honesty, but rather faith that the trusted one's honesty AND dishonesty will not bring harm our way.
I have my asbestos suit on for the inevitable flaming.
