We can go back to 1968 when North Korea hijacked our naval intelligence ship USS Pueblo as a reminder for the basis on how to address North Korea today.

Then as today, Russia collaborated with North Korea as does Iran. North Korea dispatched 2 MiG fighter jets along with several attack submarines in the capture of the Pueblo. At the time was also the Vietnam war of which Russia provided unmeasured military support to North Vietnam and did not want to add another theater of conflict with the United States, as noted by the Blue House raid.  noted by the In fact, China cannot be overlooked either for many reasons.

Newly placed U.S. Secretary of State Rex Tillerson is traveling the region meeting with Asian leaders on the matter of stopping North Korea. The question is how far and wide are these talks with regard to additional countries cooperation with North Korea.

As for Iran and North Korea, The Telegraph reported the following:

The Shahab-3 is a modified version of North Korea’s Nodong missile which itself is based on the old Soviet-made Scud.

The Nodong, which Iran secretly acquired from North Korea in the mid-1990s, is designed to carry a conventional warhead. But Iranian engineers have been working for several years to adapt the Shahab-3 to carry nuclear weapons.

“This is a major breakthrough for the Iranians,” said a senior US official. “They have been trying to do this for years and now they have succeeded. It is a very disturbing development.”

The Shahab 3 has a range of 800 miles, enabling it to hit a wide range of targets throughout the Middle East – including Israel.

Further in 2015, Forbes reported collaboration between Iran and North Korea where the exchange of engineers and scientists between the two countries is common:

North Korea and Iran are believed to be exchanging critical stuff – North Korean experts and workers remaining in place while Iran sends observers to check out intermittent North Korean missile launches and see what North Korea is doing about staging a fourth underground nuclear explosion.

The nuclear exchange revolves around North Korea’s program for developing warheads with highly enriched uranium – with centrifuges and centrifuge technology in part acquired from Iran. At the same time, North Korea is able to assist Iran in miniaturizing warheads to fit on missiles – a goal the North has long been pursuing – and also can supply uranium and other metals mined in its remote mountain regions.

“North Korea continues to supply technology, components, and even raw materials for Iran’s HEU weaponization program,” says Bruce Bechtol, author of numerous books and studies on North Korea’s military and political ambitions. Moreover, he says, “They are even helping Iran to pursue a second track by helping them to build a plutonium reactor.”

That assessment supports the view of analysts that Iran is counting on North Korean expertise in constructing a reactor that produces warheads with plutonium. The reactor would be a more powerful version of the aging five-megawatt “experimental” reactor with which the North has built perhaps a dozen warheads at its nuclear complex at Yongbyon, including three that it’s tested underground — in October 2006, May 2009 and February 2013, two years ago this month.

Then comes China, where the entire North Korea internet platform used by North Korea is hosted by China. Beyond managing cyber systems for North Korea, China is also collaborating with North Korea on nuclear weapons at key production sites producing lithium for thermonuclear and boosted fission research and development.

Sanctions have been placed on North Korea due to violations of UN resolutions due to the weapons of mass destruction operations which does include missiles and the nuclear program. However, North Korea has not been affected with regard to the research/development and production due to out of country front operations where China and Malaysia are involved.

Forbes also reported:

Although the UN resolutions have highly restricted North Korea’s access to the financial system on paper, the report suggests that these sanctions have not affected the ability of North Korean networks such as Pan Systems Pyongyang to finance its operations, asserting that the network maintains bank accounts in China, Malaysia, Singapore, Indonesia, and the Middle East. By conducting financial transactions under the names of its affiliates such as Pan Systems Singapore, the company has been able to maintain sufficient financial access to the international financial system that it was able to transfer funds to a supply chain of more than twenty companies in China, and has also used front companies to conduct transactions via Hong Kong-registered companies that were cleared through U.S. correspondent banks in New York. The Panel of Experts report also provides details on the interception in the Suez Canal of the Cambodian-flagged and North Korean-crew piloted Jie Shun in what it categorizes as the “largest interdicted ammunition consignment in DPRK sanctions history,” superseding the 2013 interdiction of the North Korean flagged Chong Chon Gang ship that was loaded with vintage Cuban munitions and airplane parts. The interdiction of the Jie Shun by Egypt revealed a cargo from North Korea through the Suez Canal containing 30,000 PG-7 rocket propelled grenades (RPG) and related sub-components shipped in wooden crates concealed under 2,300 tons of limonite (iron ore). The Jie Shun evaded detection by cutting off GPS during most of its journey, with the exception of transit through heavily trafficked straits and ports. The shipment from Haeju in North Korea to an undisclosed Middle Eastern destination were falsely labeled as “assembly parts for an underwater pump,” and the bill of lading showed the address of the “Dalian Haoda Petroleum Chemical Company, Ltd.”

Rex Tillerson stated that ‘strategic patience’ has run out with regard to North Korea and all options remain on the table including preemptive strikes. North Korea has launched 46 missiles since 2011 and the most recent launch was to test a super high thrust rocket steering engine which was designed by Russian blueprints and engineers.

The addition of a four-chamber steering engine further points toward a design rooted in Soviet missile technology as RD-250 and its descendants – when used on the R-36 missile and Tsiklon-2/3 orbital launchers – were coupled with a four-chamber RD-68M steering engine.

This engine adaptation in all likelihood uses Unsymmetrical Dimethylhydrazine and Nitrogen Tetroxide propellants – a more powerful combination in terms of specific impulse compared to the Nitric Acid / UDMH propellant used by North Korea’s Unha booster
