Oh, clo. I realize your level of sophistication peaked by the 3rd grade when you discovered that boys would give you cookies to climb trees if you wore a skirt, but even you should know that these are not world leaders. These are mafia thugs as represented in the movie "Goodfellas."
I'll cut you some slack, though. You wouldn't be the first to equate United Nations thugs with mafioso wise guys. There's a strong similarity.
BTW, the laughter at the U.N. was intentionally misrepresented by a lying Press. It wasn't meant to be derogatory, but was a shocked reaction to President Trump's extremely honest and blunt statement. All they've heard is how awful the United States is. They weren't expecting the President to begin his speech with a statement about how much he has improved the country.
They aren't used to politicians being like that. He isn't boring and it's fun to hear to him talk. They laughed.
Evidence that I'm right? After the speech, a long line formed to greet the President and praise him for his speech.
