"Military solutions are now fully in place, locked and loaded, should North Korea act unwisely", Trump tweeted Friday morning. "If Kim Jong Un said he would hit Anchorage, would he say, go ahead hit Anchorage and see what happens?", Underwood said.
"He (Kim) does anything with respect to Guam or an American territory, he will regret it and regret it fast".
Trump also warned North Korea it should be "very, very nervous" of the consequences if it even thinks of attacking USA soil, after Pyongyang said it was readying plans to launch missiles toward the Pacific territory of Guam. "Whether they feel genuinely annoyed and threatened or simply see this as a way to justify more missile tests to the Chinese is a fair question".
Trump told Gov. Eddie Baza Calvo that tourism would boom on the island due to the attention it has received over the worldwide crisis. There is no such thing as an isolated nuclear attack'. It suggested building an emergency kit and having a family plan, and in the event of an attack, lying flat and avoiding looking directly at the blast.
The real danger of any pre-emptive United States strikes against North Korea's weapons' sites would be that Pyongyang might resort to using its chemical and biological weapons - and ultimately its nuclear arsenal.

Trump responded to that development by threatening to unleash " fire and fury " on North Korea if it continued to threaten the U.S.

"I take projections of casualties of thousands to tens of thousands quite seriously, and that's just in South Korea", he said.
He said North Korea had been "getting away with a tragedy that can't be allowed".
But China, North Korea's only major ally, has been urging restraint.

"At the same time, if the United States strikes first and starts war on the Korean Peninsula, China and other countries, including Russia, Japan and South Korea, will be against it".
"But Guam's former delegate to Congress, Robert Underwood, says he is concerned the 160,000 people of Guam are being forgotten with President Trump's escalating rhetoric toward North Korea".
The warm words exchanged Friday night in the US masked underlying tensions between Beijing and Washington over how to deal with the errant regime in Pyongyang. While North Korea is testing the patience of its longtime benefactor, such a scenario could lead to a unified Korea and push US troops right up to its border.
"This is a typical brinkmanship", he told CBS2's Alice Gainer. "And frankly, you could have said that for the last three presidents".
