This WikiLeaks issue is very sad, and it couldn't have come at a worse time.
It is sad that a certain group of individuals, under the banner of freedom of speech, threaten the foreign affairs of multiple countries and grow international tension. It is short-sighted, irresponsible and self-centered. When the idea of free speech was first put on paper during the Enlightenment, no one could have thought of anything nearly as powerful as the Internet. This is a clear abuse of any interpretation of the phrase freedom of speech. The concept, in its strict sense, is idealogical; you can't have complete freedom to say what you want. You can get people together for a beer and talk about working conditions. You can demonstrate against a tax raise. But you can't incite tensions against <insert social/ethnic/religious minority group name here>. It's hate speech, which is rightly forbidden. You can't use it to threaten alliances that have been so far taken for granted. If it's about revealing some behind-the-scenes conversations from <insert group/individual name here> about <insert domestic issue here>, that's what freedom of speech is for: To inform the population of their government's wrongdoing. But if a future nuclear war, and by association, the lives of billions of people, are put at stake, one must put aside abstract concepts such as "freedom of <anything>," and look at it from a different angle. It's not about philosophy anymore.
