What would happen if North Korea actually did fire missiles at the US territory of Guam?

North Korea plans to attack the tiny Pacific island this week.

NORTH KOREA SAID this week it would complete a plan within days to launch a salvo of four intermediate-range missiles towards Guam, the US island territory in the western Pacific.

It followed US President Donald Trump’s warning of “fire and fury like the world has never seen” as a war of words with the US escalates tension on the peninsula.

Would the North be able to carry out such an exercise? And could the US stop it?

Incoming: Hwasong-12

The North’s military said the plan involved four Hwasong-12 missiles, which would be aimed to come down “30 to 40 km away from Guam”.

The intermediate range ballistic missile (IRBM) flew about 787 km in its latest test in May, when it was fired at a steep angle, and is believed to have a maximum range of about 5,000 km.

That puts Guam – around 3,300 km from North Korea’s missile bases – well within range.

Analysts ruled out the possibility of them missing their targets to such an extent they hit the island instead.

The Hwasong-12 did not have “razor-sharp precision”, said Yang Uk, senior researcher at the Korea Defense and Security Forum (KODEF), describing its technology as similar to that of the Soviet Union in the 1970s.

But he added:

The missiles could miss the target area by up to five km but not more than that.

Given the intended distances declared by Pyongyang, “the chances of hitting the island by accident seem pretty low for now”, he told AFP.

Interceptor 1: SM-3

The launches – if they happen – are expected to test US missile defence systems in the region.

No North Korean missile has overflown Japan for years, although in recent months several have come down in Tokyo’s exclusive economic zone.

In the past it has warned it would shoot down any North Korean missiles that threaten its territory, and both the US and Japan are equipped with the Standard Missile-3 (SM-3) system.

It uses sheer force – equivalent to a 10-tonne truck moving at around 1,000 km hour – to destroy its target in a collision, and can operate beyond the Earth’s atmosphere to intercept ballistic missiles at high altitudes.

Manufacturer Raytheon likens the technique to “intercepting a bullet with another bullet”.

“If missiles are targeting Guam, the US will act. It’s only natural,” said Takashi Kawakami, expert on defence issues and a professor at Takushoku University.

“Japan and the US operating together, the probability of interception should increase,” he told AFP.

But it is also possible that they fail to shoot down some of the missiles.

Japan also has Patriot anti-missile systems, but they operate at lower altitudes.

Interceptor 2: THAAD

Washington has already deployed a powerful anti-missile system, THAAD (Terminal High Altitude Area Defence), in the Asia-Pacific region, including South Korea, Japan and Guam itself.

Like the SM-3, the system also uses “hit-to-kill” technology, and it was successfully tested against an IRBM for the first time last month in Alaska.

But it is designed to intercept a missile at the final “terminal” stage of its flight, so the South Korean- and Japanese-based batteries are unlikely to be effective.

And the Guam-based systems could also struggle to handle four incoming devices simultaneously, analysts say.

“THAAD might have a shot. But four targets at once would be fun,” tweeted Jeffrey Lewis of the California-based Middlebury Institute of International Studies.

“I’d add an Aegis or two,” he said, referring to the US naval weapons system designed to track and destroy guided weapons, which includes SM-3 missiles within its arsenal.

    If you are being threatened in the workplace or any other place, report them to gardai, if you get the lack of evidence reply, write up a civil proceedings charge.
    Predator behaviour needs to be held accountable.
    Their past history catches up, remember that warning

    @Dean: The WRC won’t use voice recordings but yet will listen to them, tell the bullies that they were caught on the recordings and tell the victim how awful your experience was even in writing but yet they won’t use them. While the Gardaí would, I think. What use is the WRC when getting the Gardaí would mean less hassle in most cases?

    @Dean: I suppose the best way is to report them to the Gardaí first and if there is a case then sue them in the case with emotional distress?

    Improvements needed in paperwork in WRC – lost submissions and correspondence and incorrect recording and huge delays in judgements. Also system of applying for adjournments deeply flawed and one sided. Awards when they are made are reducing so for the few who manage to take a case and win, it is not worth it much of the time. Lots of legislation to protect workers but no legal aid to assist and as costs are not awarded in statutory employment cases have to pay your own costs even if you win. Makes taking a case impossible for most. Much of the trade union assistance is not up to standard.

    Good.

    Everyone should feel respected and secure in the workplace.
