Surge in boardings of NKorean ships unlikely: analysts

NKorea blast likely less powerful than hoped: expert
The atomic bomb which North Korea tested Monday was probably less powerful than hoped because it was detonated incorrectly, according to one expert citing seismic data. The explosive, while larger than the first test in October 2006, was still far short of the expected yield of a crude Hiroshima-type bomb, according to Jeffrey Park, director of the Yale Institute for Biospheric Studies. "More than likely this means North Korea tried and failed to get a simple plutonium bomb to detonate correctly," Park wrote in an article on the website of the Bulletin of the Atomic Scientists. Park said most estimates of the Richter magnitude were in the low half of the 4.5-5 range "so it seems likely that the yield was four kilotons or smaller." While that was much larger than the 2006 test, it still fell far short of an expected 12-20 kiloton yield of a crude Hiroshima-style device, Park wrote. "For comparison's sake, the first nuclear tests of all other nations that are self-announced members of the nuclear club had larger yields than this latest North Korean test." Park said that compared to bomb technology based on uranium 235, "building a plutonium-based bomb represents a technical challenge because the critical mass can blow apart in a split second before the detonation reaches max efficiency." Even an inefficient nuclear weapon is "nothing to dismiss," Park said. "But one should be mindful of the technical challenges North Korea still faces in carrying out the threats implied by its deliberate pairing of its explosive test with test missile launches." Other experts have also estimated the power of Monday's underground blast at around four kilotons, or 4,000 tons of TNT, compared to less than one kiloton for the first test.

The United States is unlikely to begin boarding North Korean ships in search of weapons of mass destruction, despite the Stalinist state's latest nuclear and missile tests, analysts said.

But the tests are giving renewed importance to a six-year-old US-led effort that has enlisted 95 countries in an often secretive effort to prevent the spread of nuclear, chemical and biological weapons.

And South Korean and US troops were put on higher alert Thursday after North Korea announced it is scrapping the armistice that has been in force on the peninsula for more than five decades.

Overcoming its reluctance to offend the North, South Korea this week announced that it will become a full participant in the Proliferation Security Initiative (PSI).

"It sends a strong message to the North Koreans that they are not going to get away with any efforts to proliferate this technology," said Nick Szecheny, an expert at the Center for Strategic and International Studies.

But North Korea quickly drew its own line in the sand, warning on Wednesday that any attempt to board its ships would be met with "an immediate and strong military strike."

"Some of this is bluster," Szecheny told AFP. "The North Koreans like to escalate the rhetoric in order to generate hasty responses from the US and the international community. So you can't overreact. On the other hand, it is a very serious threat," he said.

It remains unclear whether the initiative has resulted in the boarding of a single North Korean ship since it was launched in May 2003 by the administration of former president George W. Bush.

Robert Joseph, a former under secretary of state for arms control, wrote in the Washington Times last year that "dozens of interdictions have taken place slowing nuclear and missile programs in Asia and the Middle East."

But US officials have provided few specifics, shrouding the program in a level of secrecy that has made its effectiveness hard to measure.

Still, analysts said it has served a useful purpose in expanding counter-proliferation efforts and techniques beyond an inner core of about 20 industrialized countries, largely the United States and its European and Asian allies.

"While maybe difficult to specify or quantify the ways in which PSI has affected North Korean behavior, it has been extremely effective in getting countries in the region to take a unified role to counter-proliferation," said Szecheny.

Some 37 multilateral exercises have been held under PSI auspices in different parts of the world, training military and law enforcement against WMD scenarios that test the legal limits of what individual nations can do.

It also has fostered intelligence sharing among participating countries about maritime or aircraft traffic.

"The idea of PSI is to loosely coordinate the actions of various countries employing their own domestic law as well as international law on maritime activities to be able to stop people when you have reason to suspect they are doing various nefarious things, especially with WMD," said Michael O'Hanlon, an expert at the Brookings Institution.

"But you do it within the confines of law as previously existing. So you stop ships in your territorial waters, for example, or if the country whose flag flies over the ship will it allow you stop ships on the high seas," he said.

That flexibility allows countries to contribute to the degree that they want, which may explain the broad participation in the initiative.

"The real benefit is now that PSI has 95, 96 participants or adherents, it has gone far beyond the core group of countries where a lot of this cooperation has been going on for some time," said Peter Crail, a research analyst at the Arms Control Association.

"And increasing their involvement in the future will be a big help," he said.

China, however, has not joined the initiative, limiting its reach in a crucial area surrounding North Korea. South Korea until now also had declined to take part because it did not want to spoil its engagement efforts with North Korea.

"The South Koreans have indicated that they are going to be focused primarily on their own territorial waters, and if North Korea were going to be exporting something it is unlikely it would be taking that route," Szecheny said.

"So whether the South Korean commitment contributes to a sudden surge of PSI activity is open to question. But its very significant in sending a strong message to the North Koreans."

China finding it harder to support NKorea: analysts
Beijing (AFP) May 28, 2009
China has long been the main ally of North Korea, but as it assumes a greater role in international affairs, Beijing will find it more difficult to defend the isolated regime, analysts say. North Korea's nuclear test this week and its threat to attack US and South Korean ships has infuriated the international community, which leaves China with less room to stand by Pyongyang's side, they say ... read more
