The mayor of Guam recorded the candid, 3-minute phone conversation with Trump and posted it to his Facebook page.
President Trump spoke with the governor of Guam on Friday after North Korea threatened earlier this week to launch missiles toward the island by mid-August.
A member of Trump's Republican Party, Calvo insisted during the two men's call that "I have never felt more safe or so confident with you at the helm", according to his office. "So with all the criticism going on over there, from a guy that's being targeted, we need a president like you, so I'm just so thankful, and I'm glad you're holding the helm, sir".
With Guam's safety in the balance, Trump assured the territory's Governor Eddie Calvo: "We are with you 1000 percent, you are safe". "Some Guam residents told reporters that they anxious what might happen if North Korea's leader, Kim Jong-un, were actually to follow through". "It looks attractive, you know I'm watching.it's such a big story in the news".
"It looks like a lovely place", he said, inviting Calvo to visit the White House the next time he is in the Lower 48. Both of these factors were specifically cited by the North Korean military spokesman who delivered the missile threat to Guam. They should have had me eight years ago, somebody with my thought process, because that was the time.
The sheet urges people to take cover as quickly as possible, "under concrete structures or below ground if possible".
"It just looks like a handsome place", Mr Trump said.
Calvo concurred, giving Trump a tourism pitch and describing it as "paradise".
"Good morning, good morning", the president is heard saying to Calvo. "In time you will be able to leave a fallout shelter".
The president called the United States military "incredible, "rock solid" and "the best in the world by a factor of five".
Trump again reassures Calvo, saying, "We'll see how it all works out but you're not going to have a problem".
But according to U.S. president Donald Trump, the threat of nuclear armageddon will be good for local tourism.
Pyongyang said in 2016 that it might blow up Guam in response to a USA anti-missile drill with Japan and South Korea it found provocative.
