My question is: did FFvC think he could give a campaign speech at the UN and the diplomats/leaders would just sit there and stay polite for his inane BS; or is he delusional enough to think they would not find it laughable? I guess secondly, I wonder if he understood that he was being laughed at in the moment and just papered it over as best he could. Personally, I suspect he got it and managed to control his reaction...
His reaction was unique, almost moment of clarity. He heard the laughing, but he seemed perhaps more confused than understanding what the laughter meant. And in a few moments, obfuscation would over rule the laughter as the UN doesn't want a strong US, so they are biased, I am great. HOOWAH!
