Donald Trump has just threatened to "totally destroy North Korea"

Donald Trump has just threatened to

"Rocket Man is on a suicide mission for himself and for his regime", Trump said, referring to his nickname for North Korean leader Kim Jong Un.

Trump's speech Tuesday was an important test on the world stage, as the United Nations grapples with global crises, including North Korea's growing nuclear program, terrorism and climate change.

A week ago, the 15-member U.N. Security Council, which includes China and Russian Federation, unanimously adopted its ninth sanctions resolution since 2006 over North Korea's nuclear and ballistic missile programs.

Trump, however, stopped short of calling for regime change, which North Korea regards as the ultimate American intention and treats as a reason for its development of nuclear weapons.

Such rhetoric has come to characterize the Trump administration's approach, which partly reflects frustration with North Korea's neighbors, China and Russian Federation.

The president says it's outrageous that some nations would trade or financially support "a country that imperils the world with nuclear conflict".

He flexed this military muscle later in his speech‚ declaring that the only thing Iran's leadership feared more than "the vast military powers of the USA"‚ was its own people.

"The United States is ready, willing and able".

Trump also took the time to promote one of his NY real estate properties before giving remarks at a meeting about United Nations reform. He called that country's dictator, Kim Jong-Un, "Rocket Man", a moniker he first unveiled on Twitter, to complaints from his critics in the United States.

He's going to try to make the case that member nations serve the interests of their own citizens when they work together and share in the burden of fighting terrorism, of propping up destabilized.

"One of the strategic implications of the speech is to point out that one of the greatest threats to the status quo in Iran is the Iranian people themselves", the White House official said.

Prime Minister Justin Trudeau, speaking in Ottawa before heading to NY, called for diplomacy in the wake of Mr. Trump's comments.

Mr. Trump calls the unfair election in the region and the starvation of freedom of its people "completely unacceptable and we cannot stand by and watch, we and all other share a goal that goal is to help them regain their freedom recover their country and restore their democracy".

He also hinted at a possible US pull out from the worldwide accord that curtailed Iran's nuclear program in exchange for sanctions relief, calling the Joint Comprehensive Plan of Action (JCPOA) an "embarrassment to the United States".

Shifting his attention to the Middle East, Trump said America will revisit its agreement with Iran to stop the Islamic country from its nuclear program.

Before taking office, Trump was dismissive of the United Nations, complaining that while it had great potential, "right now it is just a club for people to get together, talk and have a good time".

Calling it "one of the worst and one-sided transactions the USA has ever entered into", Mr. Trump warns the assembly that "you haven't heard the last on it, believe me".

Trump calls Iran Nuclear Deal an "embarrassment" to U.S.

. "But in fulfilling our obligations to other nations we also realize it's in everyone's interest to seek a future where all nations can be sovereign, prosperous and secure".

"He aims to unify the world through tactics of intimidation, but in reality he only further isolates the United States".

Israeli Prime Minister Benjamin Netanyahu, a Trump ally, wrote on Twitter, "In over 30 years in my experience with the United Nations, I never heard a bolder or more courageous speech".

He pointed to the stock market and the employment rate and says the USA military will soon be the strongest it has ever been.

"To restructure or not to restructure is no longer the question - the United Nations must be restructured for it to remain relevant in years to come".
