with the North test-firing a short-range projectile 125 miles along its coast, according to the South Korean military.

In January, Pyongyang conducted a nuclear test, followed by what it said was a satellite launch in February that was condemned internationally as cover for testing banned missile technology.

Jon, at the North Korean Ministry of Foreign Affairs, told the AP it was "ridiculous, a false argument" to say that the country's nuclear program posed a threat to other nations.

He said a nuclear arsenal was "the only way to effectively deter the persistent nuclear threat and war provocations from the US … as long as the U.S. persists in its moves to stifle our socialist system."

On Saturday, North Korea's propaganda website DPRK Today posted a computer-generated video of a submarine-launched nuclear missilerelatively high speeds even when the air within the tire is greatly reduced because of puncture and the like. The run-flat tire is provided with a side reinforcing rubber substantially in the form of a crescent on the inner cavity side of the side wall portion. Recently, an attempt is being made to form the side reinforcing rubber of a tape laminate. However, even the run-flat tire is largely deformed during the run-flat occasion, which excessively distorts the inner surface (inner cavity surface) of the side reinforcing rubber. Thus, cracking on the side reinforcing rubber is difficult to inhibit on a sufficient level by the technique disclosed in the JP2005-225278 publication. Thus, there is a need for further improvement in winding.
