North Korean attack on Guam could invoke Article 5 of NATO Treaty if carried out

That’s if members of the North Atlantic Council make the political decision that a strike against the island would invoke the key “Article 5” of NATO’s collective defence strategy that deems an attack against a member state an attack against all.

NATO spokesman Dylan White would not speculate on the possibility, but said the alliance is “concerned" by North Korea’s “pattern of inflammatory and threatening rhetoric”.

“We call on North Korea to refrain from further provocations and abandon its nuclear and ballistic missile programs in a complete, verifiable and irreversible manner, as required by the United Nations,” he told news.com.au.

“We call on Pyongyang not to raise tensions further, and to engage in a credible dialogue with the international community.”

On Wednesday, President Trump continued to ramp up his aggressive rhetoric against North Korea despite being at odds with other world leaders who deemed it unhelpful.

“My first order as President was to renovate and modernise our nuclear arsenal. It is now far stronger and more powerful than ever before,” he tweeted.

“Hopefully we will never have to use this power, but there will never be a time that we are not the most powerful nation in the world!”

It follows earlier comments in which he said North Korea would see “fire, fury and frankly power, the likes of which this world has never seen before” if it continued to push its nuclear program, leading to a threat against Guam from the rogue state.

Meanwhile US Secretary of State Rex Tillerson called for calm and said people should “sleep well at night”.

“Nothing that I have seen and nothing that I know of would indicate that the situation has dramatically changed in the last 24 hours,” he said.

Guam’s status as an “unincorporated territory” of the United States means it is essentially considered part of the country for military purposes, despite residents not being able to vote.

Following the North Korea threat, Governor Eddie Baza Calvo said he was in touch with the White House and told residents “there is no threat to our island or the Marianas”.

He also reassured worried residents an attack on Guam is “an attack or threat on the United States” and said, “Guam is on American soil”.

“We are not just a military installation ... I want to ensure we are prepared for any eventuality.”

Article 6 of the NATO treaty states an armed attack against a member is also deemed to include their territories, vessels, forces or aircraft inside that territory.

The collective defence clause was invoked for the first time by the North Atlantic Council following the 9/11 terror attacks when countries moved within 24 hours.

Within one month an alliance of nations had agreed on eight measures to be deployed in NATO’s first counter-terrorism operation. It has since been used in Syria and the wake of the Ukraine-Russia crisis.

Last month the North Atlantic Council council condemned North Korea’s launch of an intercontinental ballistic missile and called for UN-led sanctions on the issue.

“We are deeply concerned by the persistent, provocative, and destabilising behaviour of the DPRK, including both its ongoing nuclear weapons program and its numerous tests of ballistic missiles and ballistic missile technology in 2017,” a statement from the council said following the unprecedented Independence Day test.

“The DPRK’s flagrant disregard of international agreements and confrontational actions undermine regional stability, jeopardise the prospects for lasting peace in the Korean Peninsula, and pose a growing threat to international peace and security.”

Australia is regarded as a NATO “partner” state that has contributed troops to missions in the past but is not a fully fledged member.

Earlier this year, NATO Military Committee Chair, General Petr Pavel, said he had the “utmost respect” for Australian forces and the country is a “highly valued, reliable and respected partner.”

The Australian government failed to respond to questions regarding preparations for a nuclear attack from North Korea.

China, Guam and Hawaii have recently conducted preparations to ready their military and citizens.

Hawaii’s Emergency Management Authority made headlines after issuing emergency guidance advising people to seek shelter within minutes of an attack, avoid looking directly at light and staying in blast resistant shelters for up to 14 days.
