United Nations delegates openly laughed at Donald Trump during his keynote speech to the General Assembly.
The humiliating moment came just moments into his big speech in New York City.
He claimed: “In less than two years, my administration has accomplished more than almost any administration in the history of our country.”
As laughter started to bubble through the crowd, Trump insisted: “So true.”
The hilarity spread across the general assembly, growing louder as Trump halted his speech.
After what seemed like an eternity, the US President exhaled, cocked his head, laughed briefly and said: “I didn’t expect that reaction, but that’s OK.”
The moment was made yet more awkward by a tweet Trump sent in 2014.
He wrote: “We need a President who isn’t a laughing stock to the entire World.
“We need a truly great leader, a genius at strategy and winning. Respect!”
The President went on to warn Syria’s Assad regime that the US would “respond” if they used chemical weapons.
And he accused Iran of sowing chaos, death and destruction.
Trump slammed the Iran Nuclear Deal, from which he withdrew earlier this year, as “horrible”.
And he vowed to resume oil sanctions on Iran from November 5, with more sanctions to follow.
