Kerry comes across a bit as Alfredo trying to intervene with Michael Corleone's negotiations for the casino in Las Vegas. I'm sure he was representing someone in Europe, but it was not the United States of America.
My guess is that Kerry thinks he is in some position to make a deal for himself. The hubris is astounding. But this is the man who went to Iraq and badmouthed the CIC. Why do I keep getting shocked at this man? I just can't keep up with his arrogant presumptious actions no matter how hard I try.
