North Korea firing back with its response to President Donald Trump's "fire and fury" threat made on Wednesday. The back and forth -- with Guam caught in the crossfire.   

Island residents are waiting and watching. Concerned - but calm. "We're worried, but not really scared," admitted Jill Reyes.

This while President Trump's damning diatribe still on replay across the globe, in which the commander-in-chief proclaimed, "North Korea best not make any more threats to the United States. They will be met with fire and fury."

Even his secretary of state, Rex Tillerson, who stopped in Guam briefly overnight, tried to calm the chaos saying Americans should sleep well at night. "What the President was doing is sending a strong message to North Korea in language that Kim Jong Un would understand," he stated.

Consider the message received. As Pyongyang this morning responding to the president's threat as a "load of nonsense". The communist country's military also revealing its draft plan to fire four intermediate-range ballistic missiles that would not directly strike Guam but instead fly over Japan and land near the territory. "Obviously there has been some concern and some worries not only within our administration but the public, but there is also no panic and there is no need for panic," said GUam governor Eddie Calvo.

The governor responding to this latest development today, said, "With the security umbrella we have over Guam and also what there's believed capabilities of North Korea there is at this time the belief that there is no need to increase the defense threat or level of threats to Guam."

The final strategy is expected to be approved by Kim Jung Un by mid-August. For now the ball is in the president's court.

Guam resident Serge Bloh told KUAM News, "How Trump replied to it, I think it really infuriated North Korea honestly, but we'll see what's gonna happen next."
