A little late for me to comment, but why, exactly, would they lock down information sharing if not out of fear of a popular reaction? Nothing revealed so far has been any worse than embarrassing. One commenter compared the revealed diplomatic cables to things one would say to one's wife about one's mother-in-law, but which one would not say to one's mother-in-law directly. They aren't even any state secrets yet, just a bunch of "Oooh, did you see what
he said about
them?"
We found out Hosni Mubarak hates Hamas. Did Hamas not know that? Suppose they didn't... now what just changed? Are they going to get their feelings hurt? The only way this will change the relationship is if one side or the other is pressured by a popular reaction to that information being aired publicly.
Our ambassador to Libya passed on a rumor that Qaddafi is sleeping with his nurse, oooh, juicy. Or check out this, which of all the things I've read isn't just a "tee hee" and actually resembles a real scandal:
In what is widely being seen as a dangerous blurring of the line between traditional diplomacy and intelligence work, the State Department has asked its diplomats to obtain "credit card and frequent-flier numbers, work schedules and other personal information of foreign dignitaries," according to the New York Times' reporting on multiple cables dating back to 2008.
Gasp... blurring the line between diplomats and spies! Of course, for hundreds, possibly thousands of years, the most common cover for intelligence agents has been diplomacy, so this isn't exactly news. Embassies are nests of spies, yes, I have read a couple of John Le Carre novels.
The amount of non-news surrounding this "event" is just stunning. Just a whole lot of we-knew-that-already.
So by what mechanism will this pressure anyone to lock down information sharing?
