How do we know the ambassador didn't set him up? He could have said a few comments about Hillary that set the whole thing in motion.
I don't think it was simply the case of this young guy getting drunk and spilling his guts to the guy who happened to be standing closest to him. The ambassador was egging him on.
Of course he was which implicates Australia in addition to UK. The whole “Five Eyes” system is just as corrupt as internally.
I think your right, he was set up but millennials have a reputation in Washington of having loose lips.
Talked to one today who he and his wife have some government security clearances. He said in the very beginning they were kinda shocked but once they had time to think about it, it was a DUH moment. And they understood and respected their position.
