Transcript for Guam residents react to North Korea missile threat

Thanks very much. Let's talk more about Guam. As we said the U.S. Territory on Guam in the crosshairs this morning. 167,000 Americans there. Along with two major military bases and ABC's Jim Avila is on the ground with more on how they're responding. Good morning to you, Jim. Reporter: Good morning, Paula. A mixed message from the Guam government this morning telling residents to enjoy the weekend while reminding then to listen for islandwide sirens in the event of a missile attack. This morning, all eyes turn toward this small island in the middle of the pacific as its neighbor, North Korea, four hours away by plane but just 14 minutes by icbm threatens to launch missiles towards Guam's shore, a specific threat with a timetable set as early as next week. The U.S. Territory of Guam home to more than 160,000 American citizens. U.S. Naval and air bases and more than 7,000 U.S. Troops. Overnight the island's leaders urging its citizens to remain calm but posting these drawings on the government website of how to seal off doors and windows in case of attack. We don't want to put fear on the people as well. Reporter: Here on the island a mix of apathy and controlled panic. Some seemingly unaffected. I think one of the safest places to be is where they have they're aiming. Reporter: Others blaming president trump for upping the rhetoric. He's rich, good. He has all the money. He's protection. What about us. What about those who don't have any protection to help them? Reporter: Little but strategy Guam is 3800 miles west of Honolulu and 2100 miles southeast of Pyongyang. For now most attempt to act like life goes on. The locals still filling the largest complart in the world where families seem more concerned about school supplies than military hardware falling from the sky.
