Threatening to fire a volley of missiles toward a major USA military hub _ and the home to 160,000 American civilians _ may seem like a pretty bad move for a country that is seriously outgunned and has an terrible lot to lose.
He adds, "if anything happens to Guam, there's going to be big, big trouble in North Korea".
In a guidance note titled "Preparing for an Imminent Missile Threat", Guam Homeland Security advised seeking out in advance windowless shelters in homes, schools and offices, with concrete "dense enough to absorb radiation".
The small US territory of Guam has become a focal point after North Korea's army threatened to use ballistic missiles to create an "enveloping fire" around the island.
"Do not look at the flash or fireball - It can blind you".
The local government of this tiny US Pacific island issued preparation guidance to its 163,000 people on Friday on how best to hide and deal with radiation after threats by Pyongyang to strike Guam, or test its missiles in its surrounding waters.
In the fact sheet, Guam authorities advise residents to stay inside "the nearest building, preferably built of brick or concrete", for "at least 24 hours unless otherwise told by authorities". Radioactive material can spread, which is why removing clothing is vital.
"Do not use conditioner in your hair because it will bind radioactive material to you hair".
If there is no access to shower nearby, a wipe or clean wet cloth on the parts of the skin that was exposed could also be used.
Still, Dee Cruz, a senior watch officer with Guam Homeland Security, concedes that "folks here are concerned because there's a lot of talk about it" - alluding to extensive media coverage of the public statements made by Trump and his counterpart in North Korea, Kim Jong Un.
For decades, Guam has been a critical asset for the US military, housing 6,000 troops and strategic bombers capable of carrying nuclear weapons.
