The United Nations General Assembly brings together all 193 member states for the annual assembly session and general debate. This week is the UNGA’s 80th anniversary.

With so many world leaders in one space, there are always a few stand-out moments. Here are some examples from past UNGA sessions.

1960: Soviet leader Nikita Khrushchev interrupted a Philippine delegate making accusations of Soviet imperialism.

Khrushchev began by banging his fist on his desk but after nocking his watch off. As he went to retrieve it, he grabbed his shoe and switched to banging that instead.

1962: During the Cuban Missile Crisis U.S. Ambassador Adlai Stevenson made something of a TV-age breakthrough when he presented to the Security Council photo evidence of a Soviet missile buildup.

Stevenson demanded the Soviet representative answer whether missiles were being installed, adding he was prepared to wait "until hell freezes over" for the response.

1974: Yasser Arafat, the leader of the Palestinian Liberation Organization emphasized his revolutionary credentials by addressing the assembly wearing his gun belt and holster to press for Palestinian independence.

He told the world body, "Today, I have come bearing an olive branch and a freedom-fighter's gun. Do not let the olive branch fall from my hand."

But it's not just props that garner attention. Words matter.

In 2010, the U.S. delegation walked out of the GA when Iranian President Mahmoud Ahmadinejad speculated in his address that Americans were behind the September 11 terror attacks.

And in 2018, U.S. President Donald Trump boasted about what he called extraordinary economic progress under his leadership… and got a surprising response.

"In less than two years, my administration has accomplished more than almost any administration in the history of our country. America's ... so true. (laughter) Didn't expect that reaction but that is OK. (More laughter)
