North Korea's nuclear test last month wasn't just a show of defiance and national pride; it also serves as advertising. The target audience, analysts say, is anyone in the world looking to buy nuclear material.

North Korea’s belligerent rhetoric — which has included a threat to conduct a third nuclear test and launch more long-range rockets — and its description of the United States as a “sworn enemy” should compel the Obama administration to rethink its policy toward the secretive, Stalinist nation, analysts say.

New satellite images of a North Korean rocket launch site show a mobile radar trailer and rows of what appears to be empty fuel and oxidizer tanks, evidence of ramped-up preparation for what Washington calls a cover for a long-range missile test.

Japan's defense minister said Friday he had issued an order to shoot down a North Korean rocket if it threatens the nation's territory, a planned launch that has raised global alarm bells.
