>> US President Donald Trump, in his first speech before the United Nations General Assembly, Tuesday, making an all out threat against another member state.>> The United States has great strength and patience, but if it is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea.
>> It was the president's sternest warning yet against Pyongyang, for that regime's ballistic missile launches and nuclear tests. His words causing a visible ripple throughout the room. Reuter's White House correspondent Steve Holland was in the chamber.>> President Trump clearly startled people gathered in the assembly hall today.
There were loud murmurs that erupted. One person covered their face, another diplomat was clearly sort of appalled. This was very surprising language coming from Trump at this world body today. Standing before representatives of 193 nations, Trump even reviving his insulting Twitter moniker for North Korean leader Kim Jong Un.
>> Rocket Man is on a suicide mission for himself and for his regime.>> The 41 minute address included some praise for the UN's founding mission. But showed Trump remains committed to the America First rhetoric of his presidential campaign.>> I will always put America first. Just like you, as the leaders of your countries, will always and should always put your countries first.
>> We saw a fiery nationalist in Donald Trump today at the United Nations. He got rid of all sort of diplomatic niceties and issued a number of threats at nations around the world.>> The President attacked multi national trade deals.>> Millions of jobs vanished and thousands of factories disappeared.
>> Slammed the U.N. backed Iran nuclear agreement.>> That deal is an embarrassment to the United States.>> And suggested to an organization, founded on international cooperation, that self interest was in their best interest.>> We must solve our problems to build our prosperity, to secure our future, or we will build vulnerable to decay, domination and defeat.
>> The speech, read carefully from a teleprompter, followed just moments after the UN Secretary General appealed to diplomacy.>> Fiery talk can lead to fatal misunderstandings. The solution must be political and this is a time for statesmanship.>> The UN Security Council has unanimously voted to enact sanctions on North Korea 9 times since 2006.
