Analysts who have studied photos of a half-dozen ominous new North Korean missiles showcased recently at a lavish military parade say they were fakes, and not very convincing ones, casting further doubt on the country's claims of military prowess. Since its recent rocket launch failure, Pyongyang's top military leaders have made several boastful statements about its weapons capabilities. On Wednesday, Vice Marshal Ri Yong-ho claimed his country is capable of defeating the United States “at a single blow.” And on Monday, North Korea promised “special actions” that would reduce Seoul's government to ashes within minutes. But the weapons displayed April 15 appear to be a mishmash of liquid-fuel and solid-fuel components that could never fly together. Undulating casings on the missiles suggest the metal is too thin to withstand flight. Each missile was slightly different from the others, even though all were supposedly the same make. They don't even fit the launchers they were carried on. “There is no doubt that these missiles were mock-ups,” Markus Schiller and Robert Schmucker, of Germany's Schmucker Technologie, wrote in a paper posted recently on the website Armscontrolwonk.com that listed those discrepancies. “It remains unknown if they were designed this way to confuse foreign analysts, or if the designers simply did some sloppy work.” The unveiling created an international stir. The missiles appeared to be new, and designed for long-range attacks. Washington contends that North Korea's failed April 13 rocket launch was an attempt to test missile technology rather than the scientific mission Pyongyang claims. But after pouring over close-up photos of the missiles, Schiller and Schmucker, whose company has advised NATO on missile issues, argue the mock-ups indicate North Korea is a long way from having a credible ICBM. “There is still no evidence that North Korea actually has a functional ICBM,” they concluded, adding that the display was a “dog and pony show” and suggesting North Korea may not be making serious progress toward its nuclear-tipped ICBM dreams.
