Wow! Obama has really had a rough week at the G20 meeting.
First the Chinese refused to bring out an airport stairway so he could exit Air Force One and get on the ground. AF-1 has a built stairway back at the cargo door, so eventually the crew cranked it down and Obama exited that way. Then a minor Chinese airport official started screaming at the US delegation that "China is OUR country." And apparently there was a minor scuffle when one of the US reporters tried to walk away from the official delegation.
This was obviously all a pre-planned effort by the Chinese to insult Obama. The Chinese detest Obama.
Then there were the "negotiations" with Putin designed to reach an accord on Syria that obama babbled about for days. Of course there was no accord---the Russians obviously detest Obama and pictures of Putin and Obama show them locked in a stare-down contest
Lastly there was the incident where the president of the Philippines said that Obama was a "Son of a Bitch." Some US media are reporting it as a son of a whore, but it sounded like "son of a bitch" to me. This is remarkable behavior at a diplomatic meeting, and indicates that the Philippine leadership also detests Obama.
I'm not even sure Obama got any golfing done---it was a very tough week for Obama.
