Trump warned North Korea on Tuesday that any threats to the U.S. These defenses include the Terminal High Altitude Area Defense system at Andersen Air Force Base, the THAAD in South Korea, the Patriot defense system in Japan as well as Aegis war ships in the Sea of Japan.
"We're very concerned about the news but we've been given assurance by the local government primarily through Governor Eddie Calvo that he is working with the military to ensure that the safety of all the residents are the utmost priority", said Norman Analista, president of the Filipino Community of Guam. "There are several layers of ballistic missile defense".
If the United States has two interceptors fired at each North Korean threat "the odds of success are good", said Elleman, who said the U.S. has a 96% chance of downing each individual missile.
It was also to deploy the anti-missile system in neighbouring Ehime, NHK said.
After North Korea's second test of an intercontinental ballistic missile (ICBM) on July 28, South Korean President Moon Jae-in ordered a speedy deployment of the controversial U.S. THAAD anti-missile defense system, reversing his earlier decision to postpone it pending an environmental review.
"If the United States did try to intercept the missiles they would want to intercept all of them, because failing to intercept them all would send a message about the (US's) limited capacity. those systems aren't flawless", he said.
But even with its scattered assets across the Pacific, the USA is not on war footing towards North Korea.
But shooting down the North Korean missiles would pose a huge risk for potentially little reward.
Rather, Seoul wants to double the maximum payload to 1,000 kg or greater, powerful enough to target underground bunkers or nuclear sites within the North, the officials said.
"If it doesn't, that means you might have some sort of software or system failure and better to find that out in peacetime rather than at war".
