President Donald Trump's speech at the United Nations General Assembly on Sept. 19 received warm praise from Israeli Prime Minister Benjamin Netanyahu.
Trump focused in his speech on criticizing North Korea and Iran, which he described as a "murderous regime," reports Reuters.
Trump stated that it may be necessary to "totally destroy" North Korea, a country with a population of 26 million people. He added, referring to North Korean leader Kim Jong Un, that "Rocket man is on a suicide mission for himself and his regime."
Trump also pointed to problems with democratic rule in Venezuela and the danger posed by Islamist terrorism.
"Major portions of the world are in conflict and some in fact are going to hell," he added.
Reuters reported that some world leaders in the audience responded with surprise.
Netanyahu welcomed Trump's comments.
"In over 30 years in my experience with the UN, I never heard a bolder or more courageous speech," he wrote on Twitter, reports the Washington Examiner.
"President Trump spoke the truth about the great dangers facing our world ... and issued a powerful call to confront them in order to ensure the future of humanity," Netanyahu added.
Trump threatened to pull out of the 2015 nuclear agreement with Iran. He said the deal was an "embarrassment" and indicated that a decision on its future could come in October, when he has to decide whether to certify Iran's compliance.
"We cannot let a murderous regime continue these destabilizing activities while building dangerous missiles and we cannot abide by an agreement if it provides cover for the eventual construction of a nuclear program," he said.
Other politicians were more critical of Trump's remarks.
"It was the wrong speech, at the wrong time, to the wrong audience," Swedish Foreign Minister Margot Wallstrom said, according to Reuters.
"Trump's ignorant hate speech belongs in medieval times - not the 21st Century UN - unworthy of a reply," Iranian Foreign Minister Mohammad Javad Zarif wrote on Twitter. "Fake empathy for Iranians fools no one."
German Chancellor Angela Merkel, speaking in Germany, noted that she would work to bring about a diplomatic solution to the confrontation between the U.S. and North Korea.
U.S. Defense Secretary James Mattis said on Sept. 18 that U.S. Secretary of State Rex Tillerson is working to resolve the North Korean crisis diplomatically.
Mitt Romney, the Republican presidential candidate in 2012, endorsed Trump's speech. Romney stated that the president "gave a strong and needed challenge" to members of the U.N. to deal with global challenges.
