The juiciest bits–or at least, lots of them–can be found here, and here. I see no reason whatsoever to back away from my earlier analysis concerning the issue, but commenting on some of what has been disclosed, it would appear that Arab governments have a lot of ‘splainin’ to do, concerning their worry about Iran and its nuclear weapons program. Officials in Yemen will find themselves the targets of a backlash in their country, given the degree to which they cooperated with the United States in fighting terrorism. Of course, one now readily anticipates that these interlocutors will now clam up in conversations with American diplomats, for fear that future statements might find themselves in the public eye thanks to another massive leak.
Diplomacy is conducted via the issuance of subtle statements, and the commission of subtle activities. But it also depends on diplomats being able to let their hair down in private. That last luxury will be denied to American diplomats for quite a while, which will be detrimental to American diplomacy, and to American national security itself.
